I used this for three years in high school and recently hand-washed it, making it a little cleaner. It's a Totoro Suica case and can also hold coins. Back then, I only used it as a Suica case and didn't use the coin purse. Please refer to the photo with the pen in it (photo 7) for the depth of the coin purse. The original string was the extendable type, but it seems to have gotten tangled and now only extends 6cm. I think it would be good to use as a keychain or a coin purse. - Design: Totoro design - Material: Soft plush material - Accessory: Small green leaf charm - Zipper: With a zipper on the back - Size: Compact size Thank you for looking.
