The 2-in-1 Crystal USB Pen is a premium USB drive that combines writing functionality with USB storage. Crafted from crystal (or high-transparency crystal-like material) for the pen body, it balances practicality with decorative/gift-worthy aesthetics:

The crystal body undergoes precision cutting and polishing. Select models incorporate metal accents (e.g., gold-plated/silver-plated clips or caps), creating a premium “crystal clarity + metallic texture” combination.
Some products feature embedded logos or patterns within the crystal for enhanced recognition.
1. Writing Function: Convenient Daily Writing
The pen body houses a ballpoint or gel pen refill (typically retractable or twist-action), compatible with standard replacement cartridges (e.g., 0.5mm black ink). It delivers smooth writing performance for basic office tasks like signing documents or note-taking, eliminating the need to carry a separate writing instrument.


2. USB Storage Function: Data Transfer and Storage
Features a concealed USB port (commonly USB-A/Type-C or dual ports) with an integrated flash memory chip. Storage capacity typically ranges from 8GB to 128GB (high-end custom models may reach 256GB). Supports storing documents, images, videos, and other data for cross-device transfer. Compatible with mainstream systems including Windows, macOS, and Linux, serving as a replacement for traditional USB drives.
