This screen protector is designed for smartwatches, offering high transmission and protection. It features a 5-layer construction for durability and clarity. The package includes a wet wipe (Step 1) to remove dirt and a dry wipe (Step 2) for a clean, dust-free application. The installation guide outlines a simple process: clean the smartwatch surface thoroughly with the wet wipe, peel off the blackish protection layer (Layer 1) and place the screen guard correctly covering the edges, then peel off the upper side little bluish layer (Layer 2). This ensures a bubble-free installation and crystal clarity. The screen protector is composed of a disposable front protection film layer, a high transmission TPU layer, and a disposable back protection film layer. It is advisable to clean the surface again if required after installation. Compatible with smartwatches as shown in the images.
