These screen covers are made of Gorilla Glass, are silk printed on the back, and comes with a double sided ultra thin 3M adhesive on the back so you just have to peel, and apply them. The thickness is similar to original ones so they will sit flush on your shell. You will achieve a perfect finish to your build whenever you go Pi CM3 way with Kite's CSO or, standard GBZ with the old but still very impressive Pi Zero.
