One of my friends attended an American Association of Independent Music (A2IM) conference, and Red Stripe Beer gave away 1GB flash drives. Companies have been using flash drives as promotions for a few years now, but as you can see in the above photo, this breaks some new ground in terms of customization.
The flash drive is shaped in the form of a Red Stripe bottle, and once you remove the top half, the USB port is revealed. To help prevent losing the top, the creators thought ahead and included an additional piece of material on the keychain that the top can be attached to. Hooray!
