Dave Hakkens has created a refillable writing utensil that is almost entirely edible but still functional. A surefire way to know that someone is concentrating and most likely does not want to be bothered is when he or she appears deep in thought and is chewing ravenously at the end of a pen.
Have you ever had a pen explode in your mouth while pondering the questions of life? It’s not pleasant. Dave Hakkens had probably encountered a similar situation and finally decided to do something about it.
The pen Hakkens created is completely edible, aside from the very tiny tip with which you write. The pen seems reminiscent of candies piled atop one another. You can bite them off piece by piece or, for extra thinking juice, bite off a big piece of candy with peppermint flavor. Being deep in thought has never been so delicious.
