Two Japanese high-class packs, one price bracket, and two very different reasons to open a box. Shiny Treasure ex and Terastal Festival ex are currently sitting within a few hundred yen of each other in our stock, which means the choice between them comes down to what’s actually printed inside — not which one costs more.
Both are “high-class pack” releases in the Scarlet & Violet era, and both are currently listed as sealed boxes on our site. What separates them is the size and shape of the secret rare pool sitting behind the base set — and that’s the axis this comparison runs on.
Neither set is a reprint or a variant of the other — they’re separate releases roughly a year apart, each built around its own theme and its own chase list. What they share is the format: a smaller base set than a mainline expansion, a mirror-holo insert structure, and a secret rare tier that carries the bulk of the set’s resale value. This guide walks through both boxes card pool by card pool, compares what each currently costs sealed, and lays out a straightforward way to decide between them if you’re picking just one.
Shiny Treasure ex (SV4a) is currently listed at ¥20,176 sealed, Terastal Festival ex (SV8a) at ¥20,592 sealed — a ¥416 gap. Shiny Treasure ex runs 170 secret-rare card slots built around shiny-colored SAR/SSR pulls; Terastal Festival ex runs a tighter 50-slot secret pool built around Eeveelution and Tera-form SAR chase cards. Same budget, two different collecting goals.

Shiny Treasure ex vs Terastal Festival ex at a Glance
Both sets belong to the same “high-class pack” category Pokemon TCG Japan uses for its biggest chase-card releases, sitting a step above a standard expansion in card count and secret rare density. Here’s the side-by-side structure before we get into what’s actually in each box.
| Shiny Treasure ex (SV4a) | Terastal Festival ex (SV8a) | |
|---|---|---|
| Release date | December 1, 2023 | December 6, 2024 |
| Base set size | 190 cards | 187 cards |
| Secret rare cards | 191–360 (170 cards) | 188–237 (50 cards) |
| Total cards | 360 | 237 |
| Sealed box price | ¥20,176 | ¥20,592 |
| No-shrink box price | ¥17,340 | ¥19,032 |
| Core chase theme | Shiny (color-reversed) ex and SSR cards | Terastal-form ex and Eeveelution SAR cards |
The headline number is the secret rare count: Shiny Treasure ex packs more than three times as many secret-tier cards into its pool as Terastal Festival ex. That single structural difference shapes almost everything else in this comparison — what you’re chasing, how deep the pull pool is, and which chase cards actually move.
What’s Inside Shiny Treasure ex (SV4a)
Shiny Treasure ex released December 1, 2023, and its entire identity is built around one idea: color-reversed “shiny” Pokemon printed as SAR and SSR secret rares. The base set runs 190 cards, and the secret rare tier — numbered 191 through 360 — adds another 170 cards on top of that, giving the set 360 total cards. That secret pool is one of the largest of any high-class pack in the SV era.
The two cards that drive the set’s reputation among collectors are the supporter SARs — Iono SAR (350/190) and Penny SAR (354/190). Both are full-art trainer secret rares in the shiny-adjacent art style the set is known for. We currently carry a PSA 10 Iono SAR at ¥30,282 (update: currently sold out — restock requests via Quick Order) — a useful reference point for what a top-grade copy of the set’s headline chase card commands.
Beyond the two supporter chases, the SSR tier is built around shiny-colored ex Pokemon, with cards like Alakazam ex SSR representing the color-reversed art treatment that gives the set its name. If your goal is completing a shiny-dex or chasing the largest possible pool of alternate-art secret rares in a single box, Shiny Treasure ex is built for exactly that.
What’s Inside Terastal Festival ex (SV8a)
Terastal Festival ex released almost exactly a year later, on December 6, 2024, and takes a different approach to the same high-class pack format. Its base set runs 187 cards, with secret rares numbered 188 through 237 — 50 cards in total, less than a third of Shiny Treasure ex’s secret pool. The set carries the Master Ball / Monster Ball mirror-holo structure forward, but concentrates its chase value into a much narrower band of cards.
The set’s identity leans hard on Eeveelutions and Tera-form ex Pokemon. Eevee ex SAR (224/187) and Leafeon ex SAR (200/187) anchor the Eeveelution side, while Dragapult ex SAR (221/187) and Terapagos ex SAR represent the Tera-form chase tier — Terapagos in particular carries name recognition as the mascot of the Terastal mechanic. PSA 10 copies of both Leafeon ex SAR (currently listed at ¥21,609 (update: currently sold out — restock requests via Quick Order)) and Eevee ex SAR (currently listed at ¥15,615 (update: currently sold out — restock requests via Quick Order)) are in our graded inventory, which gives a rough sense of where the set’s top singles land relative to the box price.
With a 50-card secret pool instead of 170, Terastal Festival ex is the more concentrated of the two sets: fewer total chase targets, but a shorter list to actually complete if that’s the goal.
Box Price: The ¥416 Gap
At list price, these two boxes are about as close as two Japanese high-class packs get. Shiny Treasure ex is currently listed sealed at ¥20,176, and Terastal Festival ex sealed is currently listed at ¥20,592 — a difference of ¥416, well under 3% apart. Neither set has a meaningful price advantage over the other on the sealed box alone.
| Product | Condition | Price |
|---|---|---|
| Shiny Treasure ex Booster Box | Sealed (shrink-wrapped) | ¥20,176 |
| Shiny Treasure ex Booster Box | No shrink | ¥17,340 |
| Terastal Festival ex Booster Box | Sealed (shrink-wrapped) | ¥20,592 |
| Terastal Festival ex Booster Box | No shrink | ¥19,032 |
The no-shrink gap is a bit wider — ¥17,340 versus ¥19,032, a difference of ¥1,692. If budget is the deciding factor, the sealed prices put both sets on essentially even footing; the real decision comes down to what’s inside the box, not what it costs to buy.
It’s worth noting that a “no shrink” listing is not a discount tier on a worse box — it’s the same sealed product without the outer shrink wrap, typically because the box was opened for inspection or repackaged during handling. Collectors chasing a display-condition box for long-term storage generally want the shrink-wrapped listing; collectors buying purely to open packs often treat the two as interchangeable and go with whichever is priced lower at the time.
Chase Card Comparison
This is where the two sets diverge the most. Shiny Treasure ex’s 170-card secret pool spreads chase value across a wide field of shiny-colored ex and SSR Pokemon, with the two supporter SARs — Iono and Penny — standing out as the cards collectors specifically look for. Terastal Festival ex’s 50-card secret pool concentrates chase value into a shorter list of SAR-tier ex Pokemon built around Eeveelutions and Tera forms.
- Depth of the chase list: Shiny Treasure ex has more than three times the secret rare slots, meaning more distinct cards worth chasing across a full case — but also more competition for pull attention inside that pool.
- Named recognition: Terastal Festival ex leans on Eeveelutions (a perennial collector favorite) and Terapagos (the Terastal mechanic’s mascot), giving its chase cards a clearer “everyone knows this Pokemon” pull.
- Trainer vs Pokemon focus: Shiny Treasure ex’s headline chases — Iono and Penny — are trainer-class supporter cards, a category that consistently draws strong secondary-market interest independent of the Pokemon itself. Terastal Festival ex’s chase tier is Pokemon-card led.
- Graded reference points: PSA 10 copies from both sets are currently listed — Iono SAR from Shiny Treasure ex at ¥30,282 (update: currently sold out — restock requests via Quick Order), and Leafeon ex SAR / Eevee ex SAR from Terastal Festival ex at ¥21,609 (update: currently sold out — restock requests via Quick Order) and ¥15,615 (update: currently sold out — restock requests via Quick Order) respectively — useful benchmarks if you’re weighing box-opening odds against buying a graded single outright.
Pokemon TCG Japan does not publish official per-card pull rates for either set. Any specific ratio you see quoted online is community-reported and unofficial — treat it as a rough signal, not a guarantee, when deciding what to open.
Which One Should You Buy
Both boxes sit in the same price bracket, so the honest answer depends on what you’re actually collecting for.
- Buy Shiny Treasure ex if you want the widest possible secret rare pool in a single high-class pack, you’re specifically chasing the Iono or Penny supporter SARs, or shiny-colored ex/SSR art is what you collect.
- Buy Terastal Festival ex if you’d rather chase a shorter, more concentrated secret rare list, you collect Eeveelutions or want a Terapagos-themed piece, or you prefer Pokemon-led chase cards over trainer supporters.
- Buy both if your budget allows — at a combined ¥40,768 sealed, you’d cover two structurally different high-class packs from consecutive SV-era release years, giving a case study in how Pokemon TCG Japan varied the format year over year.
For collectors newer to Japanese high-class packs, the practical takeaway is this: card count and secret rare density are printed facts you can compare before you buy, while pull luck on any individual box is not. Decide which chase list you actually want first, then let the near-identical pricing be a non-factor in the decision.
One more angle worth weighing: if you’re building toward a complete secret-rare set rather than opening for resale value, the 50-card Terastal Festival ex list is a realistically finishable target across a handful of boxes, while the 170-card Shiny Treasure ex list is a considerably longer project. Neither is the “wrong” choice — it just changes whether you’re planning a weekend opening session or a longer-term collecting goal.
