Listing check

Found one on Mercari? Check it before you buy.

Paste the title of a Japanese secondhand listing (Mercari, Yahoo! Auctions, Suruga-ya, Mandarake…). You'll see which official item it most likely is, what the condition words mean, any signs of a bootleg, and how the price compares to the original.

We only read the text you paste. We never open the listing or store it.

Add the price and description for a better check (optional)

How it works

  1. The title is matched against a catalog of One Piece merchandise, every entry linked to its source.
  2. Japanese condition words (未使用, 箱なし, タグ付き…) are explained, and wording that often signals a bootleg is flagged.
  3. If you add the price, it's compared with the item's original price. When the match isn't confident, we say so instead of guessing.
