4-piece set of pants: 3 from Muji and 1 from Nishimatsuya The black, charcoal gray, and light gray pants (3 pairs) are all Muji baby pants. Only the brown half pants are from Nishimatsuya. Size: Only the charcoal gray is 90cm. All others are 80cm. The black and charcoal gray Muji pants are cooling type, thin and smooth, so they should be useful during this season. I don't think there are any noticeable scratches or stains, but there is some pilling and fading due to wear. Please only purchase if you understand that these are used items worn by a child and stored at home.
