I recently found an old USB Pendrive that I had since early 2008.  This was at that time one of the smallest USB drives around and it still probably is.

It came in a white square box, slightly smaller than a CD cover and about the same thinkness.

On the front of the USB Drive, it had the 6 main characters from “The Adventures of Hello Kitty and Friends” animated TV series.  They are pochacco, badtz maru, hello kitty, dear daniel, my melody and keroppi.

I am not sure if you can see the size of it, but it is basically narrower than your USB port on your PC and about 3 mm thick.  It has a 1GB capacity and can be easily hooked up to your keys.

Oh … this was taken with my new digital camera ^_^
