The display protection made of specially hardened Japanese glass is only 0.4 mm thick, but extremely hard, scratch-resistant, and equipped with an anti-fingerprint coating. The display protection glass is produced through a complex process, ground with industrial diamonds, cleaned, polished, and repeatedly checked for flawless quality. The result is an extremely hard display protection glass of the highest quality, which has nine times the hardness of conventional glass. Additionally, it is very easy to apply – the adhesive layer is made of silicone, which connects to the smartphone display in such a way that no air bubbles form.
