Why use plastic if you can use wood to build a case for a USB thumb drive?
The wooden USB stick has 2GB of storage and can be worn like a necklace.
Measurements of the eco drive are 55x26x10mm (approx.) and the weight is 13g. The simple design is pretty neat. The strap holds the plug cover in place and you also cannot loose the cover as it hangs on the strap.
Brando sells the Wooden USB drive for $32.
