100 Yen Coin-Compatible Shopping Cart Coin Substitute Keychain This keychain has a rounded end that is almost the same size as a 100-yen coin, allowing it to be used in place of a coin, eliminating the need to search for change or make change. It's a keychain type, so it's easy to keep on hand and can be taken out quickly. Shipped in simple packaging. It's cute with a four-leaf clover mark. Glücksbringer is German for "bringer of luck" or "lucky charm." *There is no guarantee that it can be used in all carts, and it may not be compatible depending on the shape (it can be properly released by pushing it in firmly).
