These are GU size 80 Sanamaru pants. I bought them for my child to change into at daycare. They were not used very often. There are traces of a name sticker on the tag. These blue pants are made of polyester and have a back pocket, making them practical. - Brand: GU - Size: 80 - Material: 93% polyester, 7% polyurethane - Color: Blue - Design: With back pocket Size: 80cm
