Building upon a core of high-clarity transparent PET, the 3.8s Crystal Film (Model: PEOOTF) features a sophisticated three-layer design. The main film boasts a precise thickness of 38μ ±5μ, ensuring robust defense against scratches and abrasions without adding bulk. The key differentiator is its advanced Permanent Acrylic Adhesive system. This specialized adhesive ensures an instant, bubble-free application—achievable in seconds—and forms a durable, long-term bond that will not yellow, ooze, or leave residue over time.

Further enhancing its premium quality, the film is backed by a ultra-thin and crystal-clear PET release liner of 19μ ±1μ. This precision-engineered liner provides superior protection for the adhesive during handling and allows for flawlessly clean and easy removal before application. With a total product weight of 30g ±2g, the film maintains a featherlight presence on devices.
