This item was received from someone else. It was unopened, but I opened it for the photos. It is unused. 17.3 x 10.5 cm 2 sheets included [Compatible Models] Steam Deck-specific glass film. 2 x Screen Protectors [9H Hardness, Shatterproof] Uses high-quality Asahi Glass from Japan, the industry's highest hardness. With a special shatterproof design, it won't shatter even if broken, ensuring safety. [High Transparency] With a high transparency of over 99%, it preserves the original image quality and vivid colors, maintaining a clear and beautiful screen even after long hours of use. [Water-repellent, Oil-repellent, Anti-fingerprint] The Asahi Glass material is treated with fluorine coating and plasma spray, and the fluorine film formed on the surface strongly repels water and oil, achieving a smooth texture. Fingerprints can also be easily wiped off. [Easy Application] The silicone adhesive layer of the film makes it easy to apply, just adjust and gently place it on top, preventing air bubbles. It's a thin and lightweight design, as if you were just holding the device itself.
