This is an odor-eliminating diaper pouch. It's compact and convenient. I bought it new, but I already had another one, so I never actually used this one for diapers. I put a clean plastic bag inside and occasionally carried it around, but it had nothing to do with diapers. It's a waste, so would someone like to use it? I have no pets and I don't smoke. The retail price was about 2000 yen.
