Here's a life-changer: it's a pen, and it's made of candy. Candy!
Yep, the edible pen, conceived by design student Dave Hakkens, is made up of those little candies you find on candy necklaces. But, you know, in pen form. You can simply nibble away at it as you work, although you'll probably need to exercise some planning and self-control to not end up with a nub after five minutes of work. But hey, that's just part of the fun.
