## Long description

Riff full-surface protective glass for Samsung Galaxy S21 Ultra (G998B) is a tempered Asahi glass screen protector with a 0.33 mm profile. The protector uses a liquid nano glue (Nipa, Japan) and an included UV lamp to achieve edge-to-edge fixation on curved displays, preserving screen clarity and touch sensitivity while increasing resistance to scratches and impacts.
Advantages

Made from 0.33 mm Asahi glass with 9H hardness, it offers scratch resistance, improved impact protection and high transparency for accurate color reproduction. An oleophobic coating makes fingerprint removal easier and keeps the display pleasant to touch.
