The cube-shaped crystal USB drive features a dual-material combination of “metal alloy cover + high-transparency crystal body”:
Metal Alloy Cover: Made of aerospace-grade aluminum alloy, treated with anodizing technology, it has a surface hardness of HV300+, making it wear-resistant, scratch-resistant, and highly resistant to oxidation. This effectively protects against daily oxidation and scratches.
The screw cap structure (some models support magnetic attraction) fits tightly, with an IP54 protection rating, ensuring dust resistance and splash resistance to extend the lifespan of the USB interface.
Crystal Body: Crafted from K9 optical crystal with a refractive index of 1.516 and light transmittance exceeding 92%. The cube cutting precision reaches ±0.05mm, with six regular sides. Under light refraction, it presents a crystal-clear visual effect, resembling a customized “crystal seal”.
Geometric Aesthetics: The cube shape embodies a “minimalist business style”. With a typical size of 20mm×20mm×20mm, its regular proportions offer a comfortable grip and a visually exquisite, sophisticated appearance.
Enhanced Portability: Equipped with a standard metal keychain and a 360° rotating ring design, it can be easily attached to keys or backpacks for “on-the-go storage”.

Logo Customization and Lighting Principle

Customizable Logo Types
- 3D Inner-Carved Logo: 3D patterns or text are laser-carved inside the crystal. Leveraging the crystal’s light refraction property, it creates a floating visual effect with a precision of 0.1mm, supporting complex graphics (e.g., corporate logos, product models).
- Flat Laser Engraving: Text or patterns are etched on the crystal surface with a depth of ≤0.2mm, featuring smooth edges. Suitable for simple slogans, signatures, and other minimalist designs.
- Colored Light Customization: Built-in RGB or monochrome LED lights can match corporate VI colors (e.g., Huawei Orange, Tencent Blue), achieving “brand-color lighting”.

Principle of Logo Lighting
A micro LED bead (power consumption ≤5mW) is integrated inside the crystal, activated via USB power supply (or an optional built-in button battery). Utilizing the light-guiding property of K9 crystal (where light propagates through total internal reflection), the LED light source uniformly illuminates the internal logo. In dark environments, the brightness reaches 500cd/㎡ with soft edge halos, highlighting a sense of technology while avoiding glare.
