About Capacity

Flash memory manufacturers use decimal calculation (1 GB = 1,000 MB), while operating systems use binary (1 GB = 1,024 MB). As a result, the displayed capacity on your device will be slightly less than the stated nominal capacity. This is normal and applies to all flash storage products:

• 4GB ≈ 3.6–3.8 GB
• 8GB ≈ 7.4–7.6 GB
• 16GB ≈ 14–15 GB
• 32GB ≈ 28–30 GB
• 64GB ≈ 58–60 GB
• 128GB ≈ 110–120 GB

Custom Logo Information

• Free laser engraving is available — color cannot be customized via laser.
• For color logo printing, please contact customer service for pricing.
• To customize your logo, send your artwork (JPG, JPEG, GIF, PNG, or BMP — max 5MB) via the customer service chat before payment.
• If no logo is received before payment, your order will ship within 12 hours without any logo engraving.
