Create your own custom USB key by crafting, 3D printing, moulding, or laser cutting an enclosure that stands apart from boring everyday sticks. The Uncased USB Flash Disk / Memory Stick - 2 GB is the raw innards for a longer-style USB stick which makes it very slim, but also it has a few notches that make it easy to mould or model.
It's plug-n-play so it works great with any computer or microcontroller in the Adafruit shop with a standard USB Type-A port. This unenclosed/uncased version is great for hobbyists or students who want to design their own hardware/memory stick enclosure but otherwise acts like any other USB key.
