These pajamas are made of a soft and moist material. I've worn them a few times, but there are no noticeable stains. Please refrain from purchasing if you are sensitive to used items, as this is a personal inspection and the item has been stored at home. I will fold the item, protect it from water damage, and ship it via Yu-Packet Post in an envelope or a宅配ビニール袋 (delivery vinyl bag). Instant purchase is welcome ◎ *The color may differ slightly from the actual product depending on the computer or monitor you are using. Sleeve Length: Short Sleeve
