The tempered glass by Blueo is a toughened glass, specially designed to cover and protect the screen of your tablet from scratches and other damages. The Invisible Airbag extends its coverage by 0.3mm at the edges of the toughened glass, providing more comprehensive protection and a smoother touch feel. The invisible TPU edges eliminate concerns about edge cracking, ensuring long-lasting durability. The BLUEO 3D Invisible Airbag Anti-break Tempered Glass uses a new generation precision mold sealing and integrated molding process, achieving edge durability with TPU quality and tougher glass that provides an almost invisible visual experience. It does not affect the screen's functionality.
