Protection and Design Features
Enhanced Protection
- Lens and Screen Protection: The case features raised edges around both the camera module and the screen. This design effectively prevents direct contact and scratches to the lens or screen when the phone is placed on flat surfaces. The micro-arc wrapped edges ensure perfect compatibility with screen protectors.
- Four Corner Drop Airbag: Constructed with a hard PC back panel and a soft TPU frame, the case incorporates 4-corner anti-drop airbags. These airbags, combined with the curved edge fit, effectively cushion impacts and protect your phone from damage during accidental drops.
Ergonomic Design
- Just Right Grip, Anti-drop: The surface of the phone case is treated with rubberized oil, providing a comfortable and secure grip. Non-slip stripe designs on both sides further enhance stability, effectively preventing the phone from slipping from your hand.
- Friction Resistant, Sweat Proof, Non-stick Fingerprint: The salient point design on the surface offers excellent friction resistance and prevents sticky fingerprints, keeping your case looking clean.
- 3D Buttons and Lanyard Hole: The case is designed with striped 3D buttons for easy and responsive pressing. An anti-lost lanyard hole is also included for added security and convenience.
