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.

Le opzioni principali sono:

• Incisione laser: Ideale per semplici disegni al tratto, molto resistente

• Stampa UV a colori: supporta il multicolore e i gradienti

• Stampa serigrafica: migliore per le tinte unite di grandi dimensioni

• Stampa a caldo (lamina d'oro/argento): per effetti di lucentezza metallica
