A:AnswerHi, Jess. The Belkin OVA020zz is a TemperedGlass screen protector which is chemically-engineered from high-quality Japanese glass. It is 0.33mm thin and it contains an antimicrobial agent to protect the screen protector from microbial growth. Our UltraGlass screen protectors are designed to be two times stronger than tempered glass. They are made from chemically-engineered German glass and are 0.29 mm thin.
