This high aluminum-silicon glass screen protector has undergone secondary hardening, strengthening treatment after tempering, so its density increases and protection effect upgrades. The hardness is up to 9H, super anti-scratch and highly wear-resistant. Self-adhering makes it easy to apply, with no residue left. 

• Secondary hardening treatment provides a solid defense against damages
• High light transmittance, clear display
• The black edge makes the screen film more beautiful
• These layers are applied by plasma spraying
• 0.26mm thickness but with secure explosion-proof function
• 2.5D arc edges, safe and smooth to use
• Easy to apply, no bubble
