Protective frosted shell back cover for iPhone 11 series with four corner hidden anti-fall airbags, made from high-quality TPU material with a hard scratch-resistant PC layer, available in solid black, green, purple and red colours.
Protective Frosted Shell Back Cover for iPhone 11 Series with Hidden Corner Airbags

This protective back cover is designed for the iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max, combining a practical defence system with a clean, minimalist aesthetic. It addresses the need for reliable drop protection without adding bulk or a flashy design. The cover's core value lies in its dual-material construction, which pairs a shock-absorbing TPU frame with a rigid, scratch-resistant polycarbonate outer shell. Available in solid black, green, purple, and red, this frosted cover offers a straightforward solution for users seeking impact protection and a muted, textured finish for their device.
Features and Construction

The cover's protection is built around a specific engineering approach, focusing on key impact zones and material synergy. It is not merely a slip-on case but a designed shell with integrated safety features.
Material and Build
The construction uses a two-layer system. The primary structural element is a high-quality Thermoplastic Polyurethane (TPU) core. This material is known for its flexibility and energy absorption. Over this, a hard Polycarbonate (PC) sheet forms the outer shell, providing the frosted texture and a first line of defence against scratches and scrapes. This combination aims to dissipate impact energy through the flexible TPU while the rigid PC resists surface deformation and abrasion.
Size and Practical Fit
Weighing approximately 30 grams, the cover is designed to add minimal heft to your iPhone 11, 11 Pro, or 11 Pro Max. This light build helps maintain the phone's handling characteristics. The cover is model-specific, with precise cutouts tailored for the camera array and ports of each iPhone 11 variant. The 'back cover' style means it protects the rear and sides of the device, leaving the screen exposed unless used with a separate front protector.
Uses and Placement

This cover is suited for various environments, from professional settings to daily commuting, where discreet protection is preferred. Its design philosophy prioritises function and a low-profile appearance.
Event or Professional Use
In professional or formal settings, the simple, solid-colour frosted finish offers a conservative and tidy look that doesn't distract. The hidden nature of the corner airbags means the protective technology is integrated without visual clutter, maintaining a clean silhouette. The scratch-resistant PC surface helps keep the device looking newer for longer when placed on tables or in bags alongside other items like keys or pens.
Everyday Home Use
For daily use around the home, office, or during travel, the four hidden anti-fall airbags target the most vulnerable parts of a phone during a drop: the corners. This design aims to cushion the initial point of impact, potentially reducing the force transmitted to the device's internal components. The TPU material's grip can also aid in handling, making the phone less likely to slip from your hand in the first instance.
Benefits and Buying Value

The value of this cover stems from its specific protective design, material choices, and the longevity offered by its scratch-resistant exterior. It is a product focused on a defined set of protective functions.
Reuse and Low Maintenance
The hard PC shell's resistance to scratches means the frosted appearance is more likely to be preserved over time, avoiding the scuffed look that plagues some clear or glossy cases. The solid-colour design does not feature printed patterns that could wear off. Maintenance is straightforward; the smooth frosted surface can be easily wiped clean with a soft cloth, supporting repeated use without degradation in appearance.
Why Choose This Product
Choose this cover if you need targeted corner protection for your iPhone 11 series device paired with a understated, matte finish. Its advantage lies in the explicit combination of a hard, scratch-resistant outer shell with strategically placed, flexible TPU airbags at the corners—a specific solution for common drop scenarios. It provides an alternative to bulky, all-encompassing cases or flimsy, decorative covers, occupying a middle ground focused on engineered impact points and durable materials.
