Geometric Green, Black, & White Sweater Size Medium

Unknown brand, but really cool green, black, and white geometric sweater. Good stretch, mid weight. Unknown material. The only tag included is the “M” size tag. About 17” pit to pit and about 24” top to bottom laid flat. Two tiny flaws noted in the last two pictures - a single green thread showing through on the front and a little run on the back of the right elbow. Smoke free/cat friendly home.
