Uniqlo Miffy rompers. I am selling these because my child has outgrown them. Set of 2! I've worn them several times, but there are no noticeable stains or dirt. I washed them with a mild acid detergent that is gentle on babies' skin. I washed them after my child stopped wearing them and stored them in a bag in the dresser! I don't have any pets. I am also a non-smoker! Please purchase only if you understand that these are for babies. They are stored at home. Please understand!
