## Long description

Flexible Glass screen protector by 3MK for the Samsung Galaxy S21 in black with a thickness of 0.33 mm provides a protective layer that preserves touch sensitivity and display clarity while fitting the device's front panel. The hybrid flexible glass construction is designed to better conform to curved edges than standard tempered glass, offering scratch resistance for daily use and improved impact performance. The black edge finish aligns with the phone frame to reduce visible borders and maintain a discreet appearance.
Advantages
The flexible hybrid construction combines the feel of glass with the bend and fit properties of a film, helping the protector adhere closely to curved surfaces. Surface hardness resists scratches from everyday objects and tools while maintaining touchscreen responsiveness. The material is engineered to absorb and disperse impact energy, reducing the risk of display damage during drops. Included installation accessories simplify alignment and application to achieve a bubble-free result.
Suitable for
Samsung Galaxy S21 owners who want full-coverage front protection with a black edge finish
Users seeking a screen protector that conforms to slight screen curvature
People who need scratch and impact resistance while preserving touch sensitivity

How to use
Prepare the phone display by powering off the device and cleaning the screen thoroughly using the provided wet cloth, then dry and remove any remaining dust with the dust-fix labels. Use the Fit-In™ positioning tabs to align the protector with the Galaxy S21 front panel, then place the flexible glass from one edge and slowly lower it into position. Use the anti-bubble card to press out any trapped air toward the edges. If needed, lift gently and reposition using the alignment tabs to correct placement before final adhesion.
Usage recommendations
For best results, install the screen protector in a dust-free environment and avoid applying excessive force when pressing the protector down; allow the adhesive to settle for several hours before placing the phone in a tight case. Clean the protector with a soft, lint-free cloth and mild screen cleaner to maintain clarity and touch performance.
