As far as I know, these have been around for a while...but what a great idea nevertheless! You can decorate awesome cakes and cookies without having to mix a lot of different colors of icing, or even know how to pipe icing, for that matter :) The colors are great and really vibrant, and all you need to know how to do is hold a pen! Genius. I found a wonderful blog the other day, called "University of Cookie"--hee hee!--and they had posted this cute set of cookies. They were giving away a set of a brand called "FooDoodler," but I know lots of companies have made them. I think I should buy some...right now!
