WOW, they mean glossy. A glossy as ultra premium photo paper.
I was concerned at first, that the rough cut edges would look amateur, but it doesn't come out to the vinyl, so don't be alarmed.
This is a dream vinyl to cut, much easier than the Cricut stuff. I just cut a 21" window decal & am very happy with the results. Crisp, clean lines, even on the separate logo which was detailed, the lines were crisp. Weeded like a dream, or the instruction sheets say vinyl should weed. I am very happy with this vinyl.
