Note: The screen protector is intentionally cut smaller than the display because the edges are curved. Better than glass: it doesn't break or shatter (not real glass, not tempered glass). Plastic armor film with 9H hardness (300g) and anti-shock layer (shock-absorbing film). Intentionally smaller than the Vivo V23e 5G back glass due to its curvature (see photos), bubble-free and can be removed without residue at any time (no adhesive). Anti-reflective (matte anti-glare), approximately 0.2 mm thin, oleophobic anti-fingerprint coating. 10 years manufacturer warranty - branded product made in Germany.
