This is a set of 5 long underwear made of 100% cotton from Nishimatsuya and Akachan Honpo. Sizes are mixed, ranging from 50-70, but all can be worn from newborn to around size 70. The ones except for the striped one have animal patterns. There are no stains or dirt, but they show signs of wear. For those who don't mind used items, how about these for a change of clothes?
