This is a short-sleeved pajama set of [Polar Bear Pants] purchased from UNIQLO. I wore it for one season, rotating it with other pajamas. I also used a clothes dryer every time, so there is a tear at the neckline (Image 4). The UNIQLO fabric is originally sturdy, and there are no visible stains, so it can still be worn. I would be happy if someone could make use of it.
