The catalog centers on two physical form factors. Choosing between them dictates how well your device handles everyday kinetic abuse.
The Stringberry snap case uses an injection-molded, hard polycarbonate shell. Measuring barely 1.5mm in thickness, it wraps closely around the device chassis to protect against cosmetic scuffs, pocket lint, and keys. Polycarbonate possesses high tensile strength, but single-layer hard shells lack elastic deformability. When dropped, a snap-style case transfers impact shock straight into the device frame. Furthermore, snap cases leave the top and bottom edge ports exposed for easy docking, which leaves the glass perimeter vulnerable to angled impacts.
The Stringberry tough case solves this vulnerability through a dual-layer composite build. The interior uses a flexible, shock-absorbing TPU liner that cradles the device edges, buttons, and rear glass. The rigid outer polycarbonate shell wraps over this rubberized boot, dispersing localized impact energy across a wider surface area. This combination bridges the gap between boutique design and physical drop resilience, sealing the vulnerable corners of modern iPhone case models and Samsung Galaxy cases.
