The flexibility of the glass lens protector is the same as the plastic material, is it tempered glass or plastic? This lens protector is a real tempered glass.

There is an easy, quick, cost-effective way to test it yourself, and it's very accurate.

Does it come with a cleaning wipe to use prior to placing on the phone? Yes, the package includes: 3*Wet Wipe & 3*Dry Wipe 4. How can I remove bubbles? Use the kit in the package to clean the lens before placing the lens protector.If there are bubbles, try to gently press the bubbles with your finger or with a ruler,but the lens surface needs a thin cloth pad to avoid scratching the protector. 5.
