1. High hardness: material original imported of high quality materials hardness up to 9H. 2. Explosion- proof: special steel processing preventing glass film crushed open the use of safer. 3. 2.5D arc edge technology: Edge uses 2.5D arc edge technology smooth feel and durability greatly enhanced. 4. Ultra-high light transmittance: optical grade transmittance ultra-low reflection high-definition high permeability (transmittance 98% more than). 5. Oil: liquid is not easy to contaminated with and easily wipe clean. 6. Anti-Fingerprint: surface high molecular Anti-fingerprint processing eliminate ordinary membrane touch jerky feeling easy to wipe clean. 7. High sensitivity: The back-end silicone resin film full-fitting close to the screen it will not affect touch screen the touch the sensitivity when used touch response rate was even better. 8. Auto fit: of high-quality anti-static cling membrane use make product fit with the spin-off is simple easy to operate it will automatically adsorption fit the screen. You can repeat fit.
