Materials
- Full Zinc Alloy Body:
Adopts high-pressure die-casting process, with one-piece molding and no joints. The surface undergoes electroplating + mirror polishing, boasting both drop resistance and anti-oxidation properties;
The USB interface seamlessly connects with the main body, ensuring plug-and-pull stability.

- PU Leather Case Craftsmanship:
Selected high-density wear-resistant PU leather with an anti-fouling coating on the surface, offering a delicate touch;
The leather case and metal body are fixed via laser-etched card slots + high-strength adhesive bonding, with a tensile strength ≥ 8N, eliminating the risk of detachment. - Metal Key Ring:
Adopts a 304 stainless steel ring, connected to the USB flash drive body via a zinc alloy fastener, enabling integrated carrying of “USB drive + keys”. This completely addresses the pain point of “USB drives being easy to lose”. It is compatible with backpacks and car keys, serving as a “readily accessible” storage tool that balances fashion and practicality.

Design Highlights

- Curved Aesthetics: The USB flash drive body features an “S-shaped whistle contour” design, creating a visual contrast between the hardness of metal and the softness of leather. It fits the palm when held (ergonomic design, improving grip comfort by 40%);
- Cap Protection: The leather cap, in the same color as the main body, tightly wraps the USB interface (protection class IP42, dustproof + scratch-resistant).
- Color Contrast: Metallic silver forms a striking contrast with PU leather cases (available in black, red, orange, green, etc.), retro and other diverse styles, making it an aesthetic standout among “high-end gift leather USB flash drives“.
