Yes, gradient color patterns can be customized on wristband USB drives. Using sublimation transfer printing, the designed gradient pattern is first printed onto transfer paper. Then, through high temperature and pressure, the dye sublimates and permeates into the silicone or PVC rubber material. High color fidelity: Smooth multi-color transitions (such as rainbow colors or gradient blocks) can be achieved, supporting photo-level precision.

The MOQ for wristband USB drives is generally 100 pcs per style. For custom logos, the minimum order quantity varies depending on the production method:
1. Sublimation Transfer / Digital Direct Printing: MOQ is 200 pcs
2. Screen Printing: MOQ is typically 100-500 units. Smaller orders (e.g., 100 pcs) incur significantly higher per-unit costs due to shared plate production expenses.

Common materials for wristband USB drives include PVC soft rubber and silicone, with some also using leather + metal or fabric.
1. Silicone: Soft and skin-friendly, suitable for extended wear. Supports logo customization via sublimation printing, screen printing, laser engraving, etc., enabling gradient colors, 3D patterns, and high-precision logos.
2. PVC/Rubber: Highly flexible and rollable for storage. Fits snugly around the wrist. Cost-effective for bulk customization with limited budgets (e.g., promotional gifts).
3. Fabric: Lightweight and breathable, ideal for summer wear or extended use. Compatible with embroidery and heat transfer printing for textile-style designs.
4. Leather: Features a refined texture that exudes quality, making it ideal for high-end settings like business conferences or luxury promotions. Supports embossing and foil stamping for custom brand logos or textures.

The length of wristband USB drives is not fixed but varies within a range. PVC and silicone wristbands typically measure 180-220 mm, with adult sizes around 210 mm and children’s sizes between 150-160 mm.
Some silicone “snap-on wristband USB drives” are designed to stretch up to 250 mm (9.8 inches) and retract to snugly fit the wrist.
