It's super convenient, eliminating the hassle of searching your wallet for a 100-yen coin!! Have you ever been inconvenienced by not having change because supermarkets are increasingly using smartphone payments like PayPay for their 100-yen cart systems? With this keychain, you won't have to search for change or exchange money. If you attach it to your house keys, car keychains, etc., you won't have to worry about forgetting it. ※Please note: (1) It may not be compatible depending on the shape. There is no guarantee that it can be used with all carts. Please refrain from forcing it in or using it improperly. (2) It seems to take a knack to use it with Sandy's carts. It seems to work if you insert it at a slight angle. (3) Our shop is not responsible for any damage to the insertion slot caused by using this cart key, so please use it correctly with your understanding. (4) Please refrain from purchasing if you are looking for the quality of a product made in Japan, as this is imported from overseas.
