Black underwear, size 120, using HEATTECH technology. - Brand: UNIQLO - Model Name: HEATTECH - Size: 120 - Color: Black Thank you for viewing. Purchased about 2 years ago and stored at home. Never opened. I'm selling these because my child has outgrown them. The listing is for a set of two, but I have four in total, so I'm open to negotiating a deal for all four, or for individual items.
