This is a Uniqlo cotton undershirt, size 130, designed to be warm. It was sold a few years ago under the name "Warm Cotton Innerwear" for winter, and my child wore it because of its good feel and warmth. It was black, but it has faded slightly, so please use it as an inner layer. - Size: 130 - Material: 92% cotton, 8% polyurethane There may be oversights, but please understand that it has been stored at home and may have fold marks. Thank you for your purchase. Thank you for looking.
