## Long description

Riff full-surface tempered protective glass for Samsung Galaxy S21 (G991) is a complete screen protection kit that includes a 0.33 mm Asahi glass protector, a tube of liquid nano glue and a UV lamp for curing. The protector is designed for curved-edge displays and provides edge-to-edge coverage using liquid adhesive across the whole surface to ensure uniform fixation and long-lasting adhesion without affecting touch sensitivity or clarity.
Advantages
The protector uses a Japan-made Nipa liquid glue and UV curing to achieve secure, bubble-free adhesion from edge to edge. Made of 0.33 mm Asahi glass with 9H hardness, it resists scratches and helps protect the screen from minor impacts. The oleophobic coating reduces fingerprints and facilitates cleaning while the high-transparency Japanese material preserves vivid colours and sharp image quality.
