The CELLBEE Premium bulletproof glass consists of a complex mixture of real glass and a plexiglass part. Compared to cheap providers who use a lot of Plexiglas, we want to guarantee constant security through the glass. If you take more of the real glass, the bulletproof glass breaks a little faster and is more expensive to produce. In return, the display does NOT break in the event of a fall and is optimally protected. This is not the case with cheap bulletproof glass. These never break, so the following situations arise: The iPhone display is broken, but the armored glass is still intact. THAT won't happen to you with CELLBEE. Consistent protection since 2015.
