- 🛡️ Hardness: not lower 9H (Mohs scale – only such glass will withstand contact with metal objects
- 🌈 Oleophobic coating: should be applied evenly (checked with a drop of water - if spreading, the coating is weak)
- 🔄 Round cutout: for a camera with a diameter of 4.5 mm (universal with a square cutout will not work)
