Border Case 4smarts Defend iPhone 17 Pro Max Black 17.5 cm

The 4smarts Defend Border Case for iPhone 17 Pro Max provides protective coverage tailored to devices with a maximum screen size of 17.5 cm (6.9"). Its black finish combines a slim profile with reinforced edges to help reduce damage from everyday drops and scratches while maintaining access to ports, buttons and camera openings. Constructed from a mix of thermoplastic polyurethane (TPU) and polycarbonate (PC), the case balances impact absorption with structural rigidity for reliable daily use.

Advantages

The dual-material construction uses TPU for shock absorption at the borders and PC for a stable back shell, offering a balance between flexibility and strength. The precise cutouts and tactile button covers preserve full functionality of the iPhone 17 Pro Max without adding excessive bulk. The black colour provides a neutral, professional look that coordinates with most devices and accessories.
