Gray long-sleeved cut-and-sew shirt, size 100cm, made of polyester for comfortable wear. - Color: Gray - Style: Long-sleeved cut-and-sew shirt - Size: 100cm - Material: Polyester Thank you for viewing. This is a discontinued cotton ribbed cut-and-sew shirt. It can be used for a wide range of purposes, from formal innerwear to nursery school wear, and above all, the fabric doesn't wear out or get fuzzy even after repeated washing! It's a piece I wish Uniqlo would re-release.
