It's a standard card size, so it seems like it could be used for things other than a Sushiro card! There's also a zipper on the side, so it looks like it could be used to hold coins or small items! Please purchase only if you understand that this item is stored at a private residence by a non-professional (⁎ᴗ͈ˬᴗ͈⁎) I will compress it for shipping!
