I purchased these markers to write on rolled fondant "post-it notes" that I put onto a retirement cake for a coworker. I liked that this set was inexpensive and I did not have to purchase a $15-$20 set, when I only needed a few colors. The markers worked just fine and several people thought that the post-it notes on the cake were real at first! At this low price, this would be a good thing to buy to let children decorate cakes, cookies or any other food with a reasonably smooth surface. They'd have a ball, and they are so proud of their creations!
