One Piece Man Choco

One Piece Man Choco (ワンピースマンチョコ) is a collaboration between One Piece and the Bikkuriman line of wafer snacks produced by Lotte. The product follows the concept of Bikkuriman, consisting of a chocolate and peanut wafer with a collectible seal inside the package. The seals of One Piece Man Choco feature characters from the One Piece series, with a few Bikkuriman character crossovers.

Standard Products
The standard One Piece Man Choco line-up has a unique logo modelled after the Bikkuriman logo. The artwork on the collectable seals is created by GREEN HOUSE Inc., the same company responsible for the ordinary Bikkuriman products and other Bikkuriman collaborations. Each One Piece Man Choco wafer package has two alternate designs.

On the back of a collectable seal, there is a number designation, a short description of the character, and trivia tidbit called a "rumor".
