This is a pajama set from HIMAWARI Channel! This is a set of 3 items: thin long pants, long-sleeved shirt, and short-sleeved shirt, sold as a set of 2. Individual sales are not possible. The short-sleeved shirts were both worn once, maybe? There's no feeling of wear and tear, and I think they're almost the same as new (*´꒳`*) The long pants and long-sleeved shirt sets were also worn a few times, so there are no noticeable stains and they are in good condition!
