This is a mock neck sweater from UNIQLO. It's black with thick ribbing. Although the ribbing is thick, it's warm without making you look bulky ^_^ There are a few pills on the inside of the neckline, but there are no noticeable pills on the surface of the sweater, and there are no stains. Personally, I don't mind, but there is a slight feeling of wear and some fuzziness. It may be difficult to see, but please check the photos. When shipping, I will fold it compactly and wrap it, so please understand.
