Uniqlo Pajamas Short Sleeve Size 90, Set of 2 There are no noticeable scratches or stains, but they show signs of wear. How about these for changes of clothes in the summer, when they sweat a lot? Uniqlo's fabric is sturdy, so they are comfortable to wear and don't easily get pills even after washing. These are items used by a child. Please refrain from purchasing if you are sensitive to used items. Thank you.
