I believe the red one was originally a wet towel case. It has been stored for a long time without being used. There is some slight soiling, but I think it can be used not only as a wet towel case but also as a pen case! The yellow one has not been opened, so I think it's clean, but both are retro items, so please understand the deterioration. It has some thickness, so I will ship it with simple packaging. I also have various other Hello Kitty goods for sale. Please take a look if you'd like.
