One box says “Snow Hazard.” The other says “Clay Burst.” Between them sits a deck case with Iono’s face on it, and that’s the part most price guides skip past.
The Snow Hazard & Clay Burst Pokemon Center Gym Set bundles a full sealed booster box of each 2023 expansion — SV2P Snow Hazard and SV2D Clay Burst — with a run of Iono-themed supplies that never went through general retail. It’s not a new card set with its own checklist. It’s a distribution channel: the same two packs everyone else can buy, packaged once through Pokemon Center and Pokemon Card Gym locations with gear you can’t buy separately.
This guide covers exactly what’s in the box, what it originally cost, why there’s no guaranteed chase card inside despite the “gym set” name, and where a sealed copy is listed today. We ship Japanese sealed product out of Tokyo, so we’ll walk through the box as we’d describe it to a buyer before they check out.
The Snow Hazard & Clay Burst Pokemon Center Gym Set pairs one sealed box of each 2023 expansion with Iono-branded deck shields and a deck case — it carried a ¥12,800 MSRP at its April 14, 2023 release and was never sold outside Pokemon Center / Pokemon Card Gym. A sealed copy is currently listed at ¥25,200 (roughly $155 at ¥163/USD, our July 2026 reference rate).
What’s Actually Inside the Box
The official product name is 「拡張パック スノーハザード&クレイバースト ポケモンセンター・ジムセット」 — the Snow Hazard & Clay Burst Pokemon Center Gym Set, widely nicknamed the “Nanjamo (Iono) Set” after the character featured on the supplies. It’s a bundle, not a standalone card set, and the contents are fixed:
| Item | Quantity |
|---|---|
| Snow Hazard (SV2P) booster box | 1 box (30 packs) |
| Clay Burst (SV2D) booster box | 1 box (30 packs) |
| Iono deck shields | 1 set (64 sleeves) |
| Iono deck case | 1 (includes 2 divider cards) |
| Card storage box | 1 (includes 4 dividers) |
The two booster boxes are the same product sold individually at retail — a full Snow Hazard box and a full Clay Burst box, unmodified. What you can’t get by buying those two boxes separately is the supply set: 64 Iono-branded deck shields, a matching deck case with two built-in dividers, and a card storage box with four dividers for organizing a growing collection. That’s the entire value-add of the bundle over buying the packs on their own.
No Exclusive Chase Card — Here’s What the Packs Actually Contain
It’s worth stating plainly, because it’s easy to assume otherwise from the name: the Gym Set does not include a guaranteed exclusive card. The packs inside are pulled from standard Snow Hazard and Clay Burst production, sealed and randomized exactly like packs sold through any other channel. There is no Gym Set-only card number, no bonus promo, and no upgraded hit rate built into this bundle.
The pull odds for the SR, SAR and other chase cards in each set follow the same distribution as the standalone boxes covered in our Snow Hazard pull rates guide and Clay Burst pull rates guide. If you’re buying this set specifically to chase a card, treat it as two ordinary boxes — the odds don’t change because of the packaging.
What is exclusive to this release is the character theming itself. Iono (Nanjamo) headlines the supply set’s artwork, and if you’re specifically collecting her cards rather than sealed product, our Iono cards guide covers her printings directly — the Gym Set’s shields and deck case are supply items, not cards, so they sit outside that card-by-card breakdown.
You’re paying for two standard boxes plus branded accessories, not better odds. If pull rates are your only concern, compare this bundle’s price against buying the Snow Hazard and Clay Burst boxes separately before deciding.
Release Date, Price and Where It Was Sold
The set released on April 14, 2023, at an MSRP of ¥12,800 (tax included). It was not distributed through general retail. Sales ran exclusively through Pokemon Center stores and Pokemon Card Gym locations, which is standard practice for Pokemon Center-branded bundles: they’re sold alongside regular product at those specific storefronts rather than shipped to convenience stores, card shops, or other general retailers.
That distribution model is the main reason sealed copies are harder to find today than the individual expansion boxes. The standalone Snow Hazard and Clay Burst booster boxes moved through general retail and remain part of the wider Japanese sealed-product circulation; this bundle only ever moved through a narrower set of Pokemon Center and Pokemon Card Gym storefronts during its original release window, and it hasn’t been reissued since.
Why It’s Called a “Gym Set”
The “Gym Set” in the name refers to the sales channel, not a gameplay format — this bundle was sold through Pokemon Card Gym locations (the retail/event spaces that also host organized play) alongside Pokemon Center stores, rather than through general retail. The “sets” in the product itself are the two expansion packs it combines: Snow Hazard and Clay Burst, packaged together as a single release rather than two separate purchases.
This guide covers the Snow Hazard & Clay Burst / Iono release specifically. If you’ve come across a different Pokemon Center bundle also described as a “Gym Set,” don’t assume it matches the contents or pricing described here — verify the exact expansion names and character theming printed on that box before comparing it to this one. The official listing for this release is on the Pokemon Center product page.
Who This Bundle Actually Makes Sense For
Strip away the branding and this is a purchasing decision between two ordinary boxes and one bundled box plus supplies. Whether the bundle is worth it over buying separately depends on what you’re actually after:
- You want the Iono-branded shields and deck case specifically. Those items weren’t sold on their own — the only way to get them is inside this bundle, so if the supplies are the goal, the packs are effectively along for the ride.
- You want a matched Snow Hazard + Clay Burst display piece. Buying the bundle sealed keeps the original packaging and both boxes together as one release, which matters if you’re collecting for presentation rather than opening product.
- You’re only chasing SR/SAR pulls from either set. There’s no odds advantage here — check current pricing on the standalone Snow Hazard and Clay Burst boxes before paying a premium for supplies you may not need.
- You collect Iono/Nanjamo specifically. The deck shields and case are supply items with her artwork, not tournament-legal or graded cards. For her actual card printings, our Iono cards guide is the more direct resource.
