This is a used item that was used for a child. It was used for a short period and I believe it is clean with no noticeable stains, but please refrain from purchasing if you are sensitive as this is a personal inspection. ① and ② are from petit main, and ③ and ④ are from Uniqlo. ① and ② all have snap buttons, while ③ and ④ have drawstrings on the inside and snap buttons on the outside. Both were easy to put on and were very useful. They have been washed at home using Sarasa detergent.
