This screen guard offers multi-layered protection for your smartwatch. It features a high transmission TPU layer, protected by removable front and back film layers. The package includes a wet and dry wipe sachet for thorough cleaning before application. The installation process is simple, involving cleaning the surface, applying the screen guard by peeling off the blackish protection layer (Sticker 1), then peeling off the bluish layer (Sticker 2), and finally cleaning the surface again if needed to reveal crystal clarity. Compatible with smartwatches as depicted in the installation guide.
