The instructions for the jar indicate that there is a coating on the adhesive side (step 1 with a label) and a coating on the non-adhesive side (step 2). was . There is only one foil on the adhesive side, the instructions also state that a bubble popping card was in the kit, there was no card included. I was able to attach the protective glass with just one bubble which I was able to remove easily, honestly I was surprised I had more problems. It appears to be good quality glass but that just means it looks like glass, who knows if it's hard or not lol. I applied this to my wife's tablet, she will let me know if it's any better than a bare screen.
