The cases are described as being made from polycarbonate.
Listings describe the DualPro as slim or lightweight, with a textured/soft‑touch finish that improves grip while minimizing added bulk.
They use a snap‑on/snap‑closure design (described in listings as a snap closure or snap‑on case).
Descriptions highlight a soft‑touch or textured finish—phrases used include “Soft‑Touch Texture” and “Slim Textured Design”—which is intended to improve grip.
Each listing indicates one case per package (Package Quantity: 1) and specifies “Battery: No Battery Used.”
