Seem to be good quality, be careful when peeling

Seem to be very nice quality and pretty thick. If you peel them very fast you can separate the top portion from the adhesive backing. notably, however, that still leaves you with a functional insulator - it's not like the adhesive backing completely comes off, you can just separate the topmost layer of paper if you're moving too quickly / being silly.
