This screen guard is designed for smartwatches, offering multi-layered protection and high transmission. It features a 'Know your product' diagram illustrating its composition: a Disposable Front Protection Film Layer, a High Transmission TPU Layer, and a Disposable Back Protection Film Layer.

The product comes with a detailed installation guide to ensure a bubble-free application. The installation process involves cleaning the smartwatch surface thoroughly with the provided wet and dry wipes, peeling off the blackish protection layer using Sticker 1, placing the screen guard correctly, and then peeling off the upper bluish layer using Sticker 2. It is crucial to clean the screen properly before application to achieve optimal results. The package includes a cleaning kit with wet and dry wipes to facilitate a smooth installation.
