EB-04 Chase Cards: Jewelry Bonney, Koby and the Rarity Breakdown

Updated November 9, 2026

The EB-04 (EB04) chase cards in the Japanese edition of EXTRA BOOSTER -EGGHEAD CRISIS- start with the new Leader Jewelry Bonney (EB04-001, in Normal and Alt-Art versions) and the Koby card EB04-044, the set’s super alternate art card. This guide lists every card the official pages highlight, explains the rarity breakdown, and shows how to buy the box from Japan.

What are the key facts about EB-04 Egghead Crisis?

EB-04 is the Extra Booster EXTRA BOOSTER -EGGHEAD CRISIS-, themed around the Egghead Arc, and it was released in Japan on January 31, 2026. The table below gives the details that identify the product.

The Japanese official page says the set includes many characters who appeared in the Egghead Arc. Our box listing describes the arc as the Straw Hats’ confrontation with the World Government on the island of science. The English official page adds that illustrations may differ from the final product and that product details may change, so use the printed card in your hand as the reference once you have it.

Which EB-04 cards do the official pages highlight?

The official pages highlight eight card numbers: EB04-001, EB04-002, EB04-013, EB04-022, EB04-038, EB04-044, EB04-052 and EB04-058. The table lists them in numerical order with what the official pages say about each one.

The official pages do not give the rarity of every highlighted card, and they do not publish a value or a ranking. So this guide does not rank these cards against each other. It tells you which cards the publisher chose to show and which two of them come with a named special version: the Leader (Normal and Alt-Art) and Koby (super alternate art).

What does the rarity breakdown say about EB-04?

The official EB-04 page splits the 68 listed card types into seven groups, and five of those groups hold fewer than ten types: Leader (1), Secret Rare (1), DON!! Card (1), Special Cards (6) and Super Rare (9). The counts below come from the official English page.

The totals add up: 1 + 1 + 1 + 6 + 9 + 21 + 29 equals 68, which matches the “67+1” figure on the official page. Rares and Commons together make up 50 of the 68 types, and Super Rares add another 9. The official page does not describe what the Special Cards are, so this guide does not either.

The official page also notes that multiples of one card may appear and that a full set may be hard to assemble. That is the publisher’s own caution, and it is worth keeping in mind if you are collecting every card number. The page also mentions a Japanese playsheet that is available through a survey link.

This guide does not quote pull rates. The official sources do not publish them, and a booster box is a randomized product.

What do we know about Jewelry Bonney in EB-04?

Jewelry Bonney is the new Leader of EB-04: EB04-001 is described on the official page as a new Leader card and comes in a Normal and an Alt-Art version. The rarity table lists exactly one Leader Card type, so EB04-001 is the set’s Leader slot.

The official page also highlights EB04-002 Jewelry Bonney, listed right after the Leader. If you collect by character, that gives you two card numbers to look for: EB04-001 for the Leader and EB04-002 for the second Bonney. When you search for the Leader, note which version you want, because Normal and Alt-Art are listed as separate versions.

Our shop listing for the box also names Bonney among its key cards. For the complete breakdown of parallel, SP and Secret Rare cards in the set, see EB-04 Egghead Crisis Parallel, SP and Secret Rares.

What do we know about the Koby super alternate art?

The Koby card EB04-044 is the set’s super alternate art card: the Japanese official page names it this set’s super parallel card, and the English page says Koby includes a super alternate art version.

That is the full extent of what the official pages say about it. They do not give a price, a rarity label for the super alternate art, or a ranking against Bonney. Koby is one of the eight highlighted card numbers, and EB04-044 is the only one the Japanese page marks as the super parallel of this release.

If you want to confirm you have the right card, read the number printed on it: EB04 followed by three digits. EB04-044 is the Koby number, and the super alternate art is listed as a version of that card.

Which other EB04 cards does the official page name?

Besides Bonney and Koby, the official page names Sanji (EB04-052), Borsalino (EB04-058), Rosinante & Law (EB04-038), Issho (EB04-022) and Carrot (EB04-013). Each is listed as a highlighted card without further description.

• Sanji, EB04-052. Highlighted on both the English and Japanese official pages.
• Borsalino, EB04-058. Highlighted on both pages under that name.
• Rosinante & Law, EB04-038. A single card that carries two characters in its name.
• Issho, EB04-022. Highlighted on both pages.
• Carrot, EB04-013. Highlighted on both pages.

The official pages do not state the rarity of these five cards. If a seller lists one of them, check the rarity printed on the card and compare it with the version you actually want.

Which cards does our box listing name as key and chase cards?

Our EB-04 box listing names Dr. Vegapunk (all Satellites), Kizaru, Saturn, Bonney and Luffy as key and chase cards, plus Egghead-themed alt-art parallel cards. This is the shop’s own description of the box, separate from the official highlight list.

The two lists overlap on Bonney. When you identify a specific card, use the card number from the official list. For another angle on the same set, our EB-04 chase cards and pull rates guide covers the top hits.

How many packs and cards come in an EB-04 box?

An EB-04 booster box holds 24 packs of 6 cards, which is 144 cards in total. At the official suggested retail price of 220 yen per pack, tax included, 24 packs come to 5,280 yen.

That 5,280 yen figure is simple arithmetic from the Japanese official page. It is a reference for the Japanese suggested retail price only. The price for our imported box is shown on the product page (update: currently sold out — restock requests via Quick Order).

The regular box listing says the box is brand new and sealed, and shipped directly from our warehouse in Tokyo via FedEx with tracking and insurance. It also states plainly that this is a sealed, randomized product: the cards in each box are randomly packed at the factory, and individual card pulls are not guaranteed. That means no listing can promise you a particular card from the highlight list above.

How do the regular box and the damaged box differ?

The regular box is the standard EB-04 listing, while the damaged box is a discounted listing for a box with cosmetic damage to the outer carton. The damaged listing says the cards inside are unaffected.

The damaged listing explains why these boxes exist. Our Tokyo warehouse buys large volumes of Japanese trading cards every day, and staff inspect every item against defined condition standards. Boxes that cannot be sold as mint-condition products are separated from regular stock and offered at a lower price.

The damaged box photos are samples: the first image shows the regular product so you can identify the set, and the box you receive may differ. The damaged box is sold as-is, we do not respond to inquiries about this item, and returns and refunds are not accepted. Read the listing before you order. The type and extent of damage vary by item, and the condition photos are samples from the same stock.

How do you identify an EB04 card by number and version?

Identify a card by reading its printed number, which has the form EB04 followed by three digits, and then by checking the version. The official pages name versions explicitly, so use those names.

1. Match the number. Read the EB04-xxx number on the card. The numbers in this guide come from the official pages.
2. Match the version. The official page names a Normal and an Alt-Art version of EB04-001, and a super alternate art version of EB04-044. Treat each version as its own entry when you compare listings.
3. Check the printed rarity. The official pages give group counts, not the rarity of each highlighted card, so rely on what the card itself shows.
4. Remember the product notes. The official page says illustrations may differ from the final product and details may change.

This guide does not forecast where EB-04 card prices will go, and it does not quote single-card prices. If you compare listings, compare the same number and the same version.

How does EB-04 relate to other arc-themed Extra Boosters?

EB-04 is themed around one saga, the Egghead Arc, and the official page describes it as featuring many characters from that arc. Our comparison guide, EB-04 Egghead Crisis vs EB-06 East Blue, puts it next to another arc-themed Extra Booster.

How do you buy an EB-04 box from Japan and what does shipping cost?

Order the EB-04 box from our product page and select your shipping method at checkout; the shipping cost is calculated automatically from your delivery address. Most orders are processed and shipped within 5 business days after PayPal or Wise payment has cleared.

Delivery dates shown on the website, at checkout or in carrier tools are estimates. They do not include our handling time, pre-order release timing, supplier allocation delays, quality inspection holds, weekends, Japanese national holidays, customs processing, carrier congestion, weather or destination-country conditions.

Once the order has been handed to FedEx, delivery timing is controlled by the carrier and destination-country authorities. Customs inspections, import procedures, remote-area handling, peak season congestion, weather and carrier events may delay delivery. The policy states that such transit delays are outside our control and do not by themselves create a right to cancel or refund after dispatch.

You can check your order status in your customer account. After dispatch, the tracking number and the carrier’s latest delivery estimate are available from your account or the shipping confirmation email.

Which payment methods work for an EB-04 order?

You can pay by Wise bank transfer, PayPal, or a credit or debit card through PayPal, and all payments are made in Japanese yen. Wise bank transfer is the only method without the 5% payment processing fee.

Wise has deadlines that depend on one choice you make at checkout. Without a screenshot of your transfer, the order is cancelled automatically if payment has not been received within 12 hours of placing it. With a screenshot uploaded within 5 days, your order price is held for a total of 10 days from placing the order, and payment must arrive before the hold ends. The screenshot option requires an account and is not available at guest checkout.

If you pay by SWIFT, a receiving fee of JPY 611 is deducted before the funds reach us, so the page asks you to add JPY 611 to your order total. It also asks you to choose the OUR charge option so that correspondent bank fees are covered on your side. If the amount we receive is short, order processing is paused until the shortfall has been paid and confirmed.

For card payments, we never see or store your card number, expiry date or security code. Your card issuer may apply 3-D Secure authentication, which is handled between PayPal and your issuer. Any difference between the amount we charge and the amount on your statement comes from exchange rates and conversion fees set by your payment provider or bank.

What happens if dispatch is delayed or the address is wrong?

If dispatch is delayed, we will contact you by email as soon as practical with the revised estimate, and for significant delays before handoff to FedEx we may offer the option to wait or to cancel with a full refund. This comes from the shipping policy.

The policy lists examples of causes: supplier allocation changes, pre-order releases later than announced, inventory arriving later than expected, or a reserved unit failing quality inspection. Stock levels for sealed Japanese trading card products fluctuate frequently, so dispatch can take longer than the standard handling time.

Check your address before you pay. While an order is paid and its shipment has not yet been scheduled, you can update the shipping address yourself from My Account > Orders > the order. The destination country cannot be changed, and the carrier, shipping method and FedEx service level stay as selected at checkout. If shipping to the new address costs more, you will be asked to pay the difference before dispatch, and the order is held until it is settled. If it costs less, the shipping charge is not recalculated and no refund is made.

Once the shipment is scheduled, the self-service change closes. After that, the policy says we may consider only a minor correction that does not affect any shipping conditions, and only if the shipment has not been handed to FedEx. If we cannot confirm all the conditions, we will decline the request.

Which EB-04 box should you choose?

Choose the regular box if you want the listing described as brand new and sealed, and choose the damaged box only if you accept cosmetic damage to the outer carton and a sale that is as-is with no returns or refunds.

• Want Bonney or Koby specifically: a sealed box is randomized, and the regular box listing says individual pulls are not guaranteed.
• Want a regular, brand new and sealed box: the EB-04 Egghead Crisis booster box (update: currently sold out — restock requests via Quick Order).
• Want a lower-priced listing and accept carton damage: the damaged box, which is sold as-is.
• Want every card number: the official page warns that multiples of one card may appear and a full set may be hard to assemble.

For a step-by-step look at the box purchase itself, our EB-04 Egghead Crisis booster box buying guide goes through it in order.
