## Long description

The 3MK Tempered Glass Screen Protector for Samsung Galaxy S21+ 5G — HardGlass Max Black is a full-front tempered glass designed to shield the device display from daily wear.

Align the tempered glass to the front panel, starting from one edge and lowering it slowly to avoid trapping air. If small bubbles remain, press them gently toward the nearest edge with a soft cloth or the installation card. Ensure the edges are seated properly and that the black border aligns with the device bezels for proper adhesion and case compatibility.
