Never settle for the dreaded cracked screen with the ProtectPax Invisible Screen Protector. Remaining totally invisible, this system adheres to the front of your device with nanotechnology. Compatible with smartphones, smartwatches, tablets, and more, the ProtectPax uses liquid glass for superior protection properties. This material is both scratch and break-resistant with a 9H hardness. This is the same hardness as a ruby and six times harder than your current screen. To apply, first clean your screen. Next, you add the liquid glass to your screen and spread it evenly with a microfiber cloth. In ten minutes, ProtectPax reaches optimum strength. Additionally, ProtectPax helps to protect against electromagnetic radiation. Despite the 365-day adhesive hold, ProtectPax improves the touchscreen functionality of your device. With your device coming into contact with so many surfaces, the ProtectPax is a must-have for reliable protection.
