One Piece OP-17: the release details behind The World’s Strongest Warriors
Bandai’s English product page confirms the August release, pack MSRP and anniversary artwork for OP-17.
Already released, with a recently updated showcase
The World’s Strongest Warriors, numbered OP-17, is a released One Piece booster rather than an upcoming launch. Bandai lists August 21, 2026, for prerelease and August 28 for the English release. Its news index records a product-page update on September 11.
What collectors can verify
The official product details list a US MSRP of $4.99 per pack and 131+4 card types. The showcase highlights Super Alt-Art, fourth-anniversary Pirate Crew artwork and special Four Emperors cards. The publisher’s page includes the card imagery and links to the card list and recommended decks.

Keep the product facts separate from resale claims
MSRP describes the suggested pack price, not a verified current resale price. Bandai also cautions that packs can contain duplicates and that assembling a complete set may be difficult. This announcement does not establish pull rates, guaranteed chase-card contents or future card values.
