Cento AquaSECRET is a full glue tempered glass that will keep the contents of your screen secret, protected from the eyes of others thanks to the special built-in filter. Whether you are at a table with friends, on public transport or in an extremely crowded place, those next to you will no longer be able to see or distinguish the images or information displayed on your mobile phone screen. Made of tempered glass, with adhesive on the entire surface, it is easy to apply, protecting the phone's display against impact and scratches. The package includes a complete cleaning and mounting kit. Method of application: 1) carefully clean the phone screen; 2) peel off the protection from the adhesive side and position the foil on the screen, with utmost care, without applying force; 3) return to the surface of the glass with a plastic card for a complete bonding.
