USB pen drives offer a wide range of materials. In addition to traditional plastic and metal, they can also be made of wood and crystal.
Metal USB pen drives：options include high-hardness stainless steel suitable for business scenarios, lightweight and cost-effective aluminum alloy, and zinc alloy that is easy to die-cast with complex patterns.
Plastic USB pen drives：use materials like ABS plastic—low in cost and ideal for mass customization—and heat-resistant, impact-resistant PC plastic.
Wooden USB pen drives：feature wood as a distinctive material, with natural textures available in types such as raw wood, beech, maple, and bamboo.
There are also other options like soft, non-slip silicone, lightweight yet high-strength carbon fiber, and ceramic with a delicate texture. Each material has unique traits in terms of texture, durability, and suitable use cases, allowing for selection based on specific needs.

Ana seçenekler şunlardır:

• Lazer kazıma: basit çizgi sanatı için ideal, çok dayanıklı

• UV renkli baskı: çok renkli ve gradyanları destekler

• Serigrafi baskı: geniş alanlı düz renkler için en iyisi

• Sıcak damgalama (altın/gümüş folyo): metalik parlaklık efektleri için

• 3D laser – engraved illuminated：when powered on, the floating effect of the internal 3D laser – engraved design becomes visible.

First, check if the USB port is securely inserted (poor contact in some USB ports may cause insufficient LED power supply). Try testing it on a different computer or charger port.
If it still doesn’t light up, the LED bulb may be damaged or there could be poor contact in the internal circuitry. Stop using it immediately (to avoid short-circuiting and damaging the chip).
Contact after-sales service for repair. — Note: The crystal casing is difficult to disassemble. Do not attempt to open it yourself, as this may damage the seal, leading to water or dust ingress later.

Crystal cases boast high hardness but low toughness. Dropping them from heights over 1 meter or impacting hard surfaces (like tiles or concrete) will likely cause cracks or shattering. However, some premium models use “toughened crystal” or “crystal with metal edging” designs, improving drop resistance by about 30%.
Daily usage tips: Avoid placing it alone in pockets or backpacks where it may rub against keys, coins, or other hard objects (which can scratch the surface). Consider using a soft protective case. When inserting or removing the drive, grip the metal connector part rather than pulling on the crystal shell itself to prevent loosening at the connection point between the shell and the chip.
