Rockstable Stonecliff Caixa

Certified to survive 3-meter drops on concrete, the Rockstable Stonecliff Case wraps your phone in a dual-layer armor that shrugs off impacts that would shatter lesser protection. Its MIL-STD-810G rating isn't a marketing badge—it's a promise backed by 26 drops across multiple angles and surfaces.

Overview

The Stonecliff is a rugged protective case engineered for smartphones between 6.1 and 6.7 inches. A hard polycarbonate outer shell absorbs and disperses shock, while the soft TPU inner layer cushions the device and grips its edges. Integrated port covers keep dust and debris out of your charging port and speaker grilles, and the IPX4 splash-proof rating means rain or accidental spills won't reach your phone's internals.

What stands out

• Raised 2mm bezel protects your screen when placed face-down, and a 3mm raised ring shields the camera module from scratches.
• Textured anti-slip finish on the back and sides gives you a confident hold, even with wet or gloved hands.
• Built-in kickstand folds flat when not in use and props your phone at a comfortable viewing angle for video calls or streaming.
• Tactile button covers preserve the clicky feel of your volume and power keys, with precision cutouts for all ports and speakers.
• Antimicrobial coating inhibits the growth of odor-causing bacteria on the case surface.
• Made with at least 30% post-consumer recycled materials, reducing environmental impact without compromising protection.
