This is a fluffy trading card case. It can fit a B8 hard case. I put a hard case in it once at home, but I never took it outside and stored it in a bag. As shown in the third image, you can see what looks like wrinkles when held up to the light from the beginning. Please understand that this is a home-stored item and a foreign product, and purchase it with that in mind. I will take waterproof measures and ship it via Mercari delivery.
