Like all products and technology, screen protectors, too, keep being developed for the better. This is an aluminum-and-silicone glass, with 9H hardness - despite only being 0.26mm thick! It is 2.5D "arc-edges", meaning it's smooth and won't cut into your fingers when using it. It uses AB glue to attach to the screen, just remove the protective cover for the glue and attach it to your screen! Easy applying, and easy removal when needed. Compatible with: OnePlus 10T / Ace Pro Package included: 1 x Screen protector 1 x Wipes Set 1 x Dust-absorber 2 x Guide Stickers Other items not included
