The Message in a Bottle is a miniature "empty" glass bottle with a cork. Okay, so what? Well, it's also a 16GB/32GB USB memory stick.
With technology today it can sometimes feel that you have "nothing" because the digital world is unseen, even though it's actually packed with content and data.
Taking this motif of invisibility, the Message in a Bottle allows you to store your ideas in a minature bottle for safekeeping, complete with cork stopper.
