This is a long-sleeved T-shirt from MUJI. It's made of cotton and feels good against the skin. There are no noticeable stains, and I think the condition is good. The navy one has regular buttons, not snap buttons. The khaki one has a reversible design, so there are no tags or size markings, but it's size 90. There is a small decorative pocket on the striped side. I'm selling these because my child has outgrown them. Size: 90
