Luffy, Ace, and Sabo’s Brotherhood Vow on a One Piece Pin Badge

One Piece ASL Brotherhood Scratch Campaign Tin Pin Badge

A Prize Badge from Japan’s Scratch Campaign Tradition

Tin pin badges — small metal discs with a printed front and a safety-pin clasp on the back — are a staple format in Japanese anime merchandise. This one is an officially licensed One Piece piece, confirmed by the copyright marking ©O/S·F/T: those initials cover Eiichiro Oda (the manga’s creator), Shueisha (publisher of Weekly Shonen Jump), Fuji TV (broadcaster), and Toei Animation (production studio). It is not a bootleg or unofficial item.

It was never available in any shop. The “NOT FOR SALE” designation marks it as a scratch campaign prize — a promotional format common across Japan’s convenience stores, toy retailers, and variety shops, where customers receive a scratch lottery card and claim merchandise if it reveals a winning mark. Campaign prizes like this are produced specifically for that window of time, distributed only to participants, and not restocked once the promotion ends.

Luffy, Ace, and Sabo: The Brotherhood Behind the Design

One Piece, created by Eiichiro Oda and published in Weekly Shonen Jump since 1997, has sold over 500 million copies worldwide as of 2024. The anime has aired on Fuji TV since 1999 — produced by Toei Animation, it remains ongoing today — and a Netflix live-action adaptation in 2023 widened the series’ global reach further.

The three characters on this badge are known among fans as the ASL trio: Monkey D. Luffy (the main character, a rubber-bodied pirate pursuing the title of King of the Pirates), Portgas D. Ace (Luffy’s sworn older brother, a fire-power user who served as second division commander of the Whitebeard Pirates), and Sabo (the third sworn brother, later revealed to be a senior officer in the Revolutionary Army). They appear here as children, at the exact moment they sealed their brotherhood pact over shared cups. The Japanese text on the badge — “From today, we are brothers!!” — is the line spoken in that scene.

Ace’s death during the Marineford War arc is one of the series’ most emotional turning points and gave him lasting resonance among fans worldwide. Sabo’s reappearance in the Dressrosa arc — after years during which he was presumed dead — brought all three brothers back into focus simultaneously, sparking renewed interest in ASL-themed designs. The badge most likely dates from the Dressrosa era onward, though the exact production year has not been confirmed.

How Scratch Campaign Goods Circulate

Promotional prizes like this exist in a distribution lane entirely separate from retail. They are manufactured for one campaign, handed out over a limited period, and then gone from official channels. Items that do resurface afterward typically do so through Japan’s secondhand market — recycle shops and resale platforms — where individual winners occasionally list what they received. There is no restocking and no parallel retail sale. For collectors outside Japan, this separation from normal distribution is simply a defining characteristic of scratch campaign merchandise as a category.
