This is a USB flash memory device in a tough metal case with a tiny blue light that flashes when it's busy. Keep it in your pocket, your school bag, your office draw, or your tool kit.

It measures 31mm x 13.5mm x 4.5mm: it's so small, it's actually smaller than a normal USB A plug. The current devices are 128MB, 256MB, 512MB, 1GB, and 2GB. They all fit in the i-Duck.
