This is a Uniqlo Mame Kurogouchi 3D Ribbed Sweater. The size is M. The color is brown. It's a thin sweater. I've worn it about twice and stored it at home. There are no noticeable stains, but there are some wrinkles and slight wear from storage. Please understand that this is a used item before purchasing.
