PThink 2.5D Round Edge 0.3mm Tempered Glass Screen Protector for HTC One A9 with 9H Hardness/Anti-scratch/Fingerprint resistant (HTC One A9) Anti-scratch: 9H greatly intensified surface hardness which is 3 times stronger than regular PET film. 0.3mm Ultra-thin, specially 2.5D rounded edges for safety and a more precise fit. Tempered glass film provides super smooth touching as well as no lose in touch screen sensitivity. Make your screen Perfect Shatterproof: when great impact comes and the glass protector gets broken, it cracks into small pieces that are held within the film, they are not sharp, the glass film absorbs the impact so as to protect the phone screen from shattered. NOTE: This protector is designed slightly smaller than the A9 screen with all-around curved edges to prevent edge lifting and air bubbles forming of the protector when installed on the screen.
