glass. But it is so thick (0.3mm), that my Diztronic case is not able to fit well - edges are standing away. Also big top part around earphone is not protected. I definitely must buy better glass. Only positive is much better touch feeling in compare with PET protector. Can you recommend me a glass with this parameters? :
1) 0.2mm thin
2) rounded edges (for fit of diztronic plastic case)
3) as much as possible of protected area around the earphone
Thanks for the tips!
