Do you ever get hungry when your taking a test

Someone Otta make a pen that is completely edible. So here goes my Attempt at explaining how it works; first the outside will be made Of lifesavers or any type of hard candy that won't get sticky, smell, melt, or messy/disgusting when held for extend periods or when your hand gets sweaty. Also instead of graphite it will be made of a hard chocolate. This item will be sold for 3.50 for a pack of two. I will patten it and call it the edipen. I already have an amazing marketing campaign that I thought of so if anyone can help me make this happen I will appreciate it and I will help make you wealthy. Thank you for your time and have a nice day/evening.
