This is a flat bag in collaboration with Mizutama-san. It's small, just the right size to fit a wallet. I am selling one that I purchased for storage. It is unused, but I purchased it personally and it has been stored at home. I do not have any pets and I am a non-smoker, but please refrain from purchasing if you are concerned. Size: W22.5 x H22.5cm, with an inner pocket (W14 x H11cm) Material: 100% cotton Price: 2970 yen (tax included)
