Offers good protection on both sides of the security label. It's a soft, rubbery, smooth feel. The label fits in there and doesn't come out by accident. I can't comment on the sticky side as I haven't used it yet. It's good to throw in a bag, and it's secure and discreet (no obvious Apple logo visible). If you are looking for theft insurance. If you want to glue it to something and find that the sticky side isn't sticky enough, you can always use a glue gun to add some more glue, or get some of those 3M Velcro tapes so you can remove them and move them around as often as necessary.
