Denim blue pants with elastic waist, size 100cm - Color: Denim blue - Size: 100cm - Style: Elastic waist Thank you for viewing. These are Uniqlo Heattech denim pants. Size 100. My child didn't like them, so they haven't been worn much, but there is a small stain on the left knee (see photo 4). They are Heattech, so the lining is a warm material. *We are looking forward to your purchase if you understand that these are used items worn by a child.
