Sanrio Kuromi Trading Card File I have been using this. I haven't taken it outside, and it has been stored on a shelf. I think it's sized to fit regular trading cards and wafer cards. There are fine scratches on the storage film. There are no problems with use, but please understand that this is a used item. I will package it to be waterproof for shipping. I am also selling other characters. Instant purchase is welcome. No price negotiations. No individual sales.
