Stain on collar
I was disappointed to see this stain on the collar. The fit is great & feels heavy & well made. Not sure why it would be packaged with a stain on it & since it’s white it’s even more noticeable

Material and stitching so it doesn't look cheap.
Good quality for the price. Not wool. It meets my needs. I don't wear sweaters that often so buying a pricey one makes no sense. These look great when they are new.

Boyfriend liked it, however it has a weird fit
I got this for my boyfriend as he is a fan of this brand's clothes. I got him small and I am glad I did. Although it looks fantastic on him because he is him, the sweater is strangely long and has a weird tough material to it. It is not exactly soft to the touch, and it has a weird stretch. It doesn't feel like other COOFANDY brand turtlenecks he owns, so I was surprised at how stiff the material was compared to those. The color is also a bit more orange in person.
