Screen protector 3MK FlexibleGlass for Samsung Galaxy M21 — 1 pc

3MK FlexibleGlass for Samsung Galaxy M21 is a single-piece flexible tempered glass screen protector engineered to preserve display clarity and touch responsiveness while providing protection against scratches and minor impacts. Designed to match the Samsung Galaxy M21 screen dimensions, this protector combines a thin glass layer with flexible properties to resist cracking and adapt to slight screen curves, maintaining a near-original viewing experience and ensuring easy daily use.

Advantages

How to use

Clean the device screen thoroughly using a microfiber cloth and any included alcohol wipe to remove dust, fingerprints and oils.

Usage recommendations

To prolong the life of the screen protector and maintain display visibility, avoid sharp impacts and repeated heavy pressure on the same spot. Clean the surface regularly with a soft, lint-free cloth and avoid abrasive cleaners. Replace the protector if it becomes deeply scratched or damaged to ensure continued protection of the underlying display.
