1. High-strength anti-scratch: 9H hardness, much higher than ordinary film 3H hardness, rejects screen scratching. Tests show that under normal conditions of use, it can ensure that it will not scratch for 3 years;2. High definition: optical-grade light transmittance, ultra-low reflection, high-definition and high-transmittance;3. Anti-fingerprint: surface polymer anti-fingerprint treatment, fingerprint suppression is greatly improved compared with ordinary protective film (note: under current technical conditions, 100% anti-fingerprint is impossible, tempered glass high-definition film can greatly improve the anti-fingerprint effect);4. Smooth contact: eliminate the jerky contact of ordinary film,5. Sensitive response: Although the thickness is 3 times that of ordinary film, the contact response speed is even better when used.Use:PDAFit:For Amazon Echo showcolour:TransparentMaterial:Tempered glasssize:18.7 x 12 x 0.03cmPackage Contents:1 x tempered film for Echo ShowOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
