One Piece Card Game Double Pack Set DP-12: What It Is and Why You Should Grab One on 28 August

With all eyes on OP-17 The World's Strongest Warriors hitting shelves this Thursday 28 August, it is easy to overlook the second One Piece release dropping on the exact same day: Double Pack Set DP-12. If you are heading to your local game shop or placing an order this week, it is worth knowing what DP-12 actually contains before you decide how to spend your budget.

What Is a Double Pack Set?

Double Pack Sets are a recurring product format from Bandai that sit alongside mainline booster releases. Rather than a full booster box or a premium collector item, each Double Pack Set bundles two booster packs together with at least one guaranteed promo or bonus card. The format is designed to be an affordable, accessible entry point — a low-risk way to crack open packs from the current set without committing to a full display.

DP-12 is the twelfth instalment of this format, and it arrives at the same time as the flagship OP-17 boosters. That timing is deliberate: the packs inside DP-12 are drawn from OP-17's card pool, meaning every purchase contributes to your OP-17 collection and gives you a shot at the set's most desirable pulls.

What's in DP-12 — and What's in OP-17?

OP-17 The World's Strongest Warriors is a landmark release for the game. It is the 4th Anniversary set, and it carries a heavy focus on the Four Emperors and the Elbaf Arc from the One Piece story. The original four Emperors — Whitebeard, Shanks, Kaido, and Big Mom — all receive the coveted Manga Rare (Super Parallel) treatment, making them among the most sought-after chase cards in the set. From the Elbaf storyline, Loki the Cursed Prince and a giant-armoured Monkey D. Luffy headline the new character roster.

OP-17 is also a historic release from a logistics perspective: it is the first fully global simultaneous launch in the game's history, with the Japanese and English versions releasing on the same date, 28 August 2026. That means UK collectors are opening packs at exactly the same moment as players in Japan — no waiting, no spoiler-induced FOMO.

DP-12 plugs directly into this excitement by putting two OP-17 packs into your hands at a lower price point than a full booster box. For a player who wants to try the set without a large outlay, or a collector who wants a few extra chances at the Manga Rares, it is a sensible purchase.

Should You Buy DP-12, OP-17 Boosters, or Both?

The honest answer depends on what you are trying to do.

If you are a competitive player building a deck around one of the six OP-17 Leaders — Whitebeard, Shanks, Kaido, Big Mom, Luffy, or the previously mysterious sixth Leader — you will want volume. A full booster display gives you the best card-per-pound ratio and the highest chance of pulling the specific cards your deck needs. DP-12 is a supplement, not a replacement.

If you are a casual collector or picking up One Piece for the first time, DP-12 is an excellent starting point. The lower price of entry means you can test the waters on OP-17's card pool without committing to a big box. If the pulls excite you, you can always go back for more.

If you want everything on launch day, there is a strong case for grabbing at least one DP-12 alongside whatever booster product you planned to buy anyway. Launch day stock of individual boosters and displays can move quickly, and having a DP-12 on hand means you will not be empty-handed if your retailer sells out of displays faster than expected.

Finding DP-12 in the UK

DP-12 is confirmed for a UK release on 28 August 2026, the same date as the OP-17 booster display. Most UK specialist game shops and online TCG retailers that stock the One Piece Card Game are expected to carry it. As always, pre-ordering through your local game shop or a trusted UK online retailer is the safest way to guarantee a copy at retail price on launch day — popular DP releases have sold through quickly at previous launch events.

If you are attending a prerelease event for OP-17 (which began on 21 August), it is worth asking your store whether they will also have DP-12 available on the night or at the full release.

The Bottom Line

DP-12 is not the headline act on 28 August — that honour belongs firmly to OP-17 The World's Strongest Warriors and its spectacular Manga Rare Emperors. But it is a genuinely useful product that sits neatly alongside the main set, offering a low-cost, guaranteed two-pack entry into one of the most anticipated One Piece releases of the year. With the historic simultaneous global launch making this a moment the whole community shares at once, there has rarely been a better time to be opening One Piece packs in the UK.
