The core highlight of this short black gel card USB drive is its UDP packaging technology and short chip design. The black gel uses an integrated packaging technology that seals the flash memory chip, control chip, and other core components in a black gel, giving it waterproof, shockproof, and dustproof properties. This short black Gel card USB flash drive has a much shorter interface. It maintains the “card-like” form (it is almost the same size as a card, with a thickness of only 1-2 mm, and it can fit easily into a wallet or a business card holder), and it is also short enough to reduce the risk of damage to the interface when it is inserted into a computer or car audio system. This makes it especially useful in small spaces. You can customize the logo and designs on the card’s surface to create a unique “portable business card.”
