I ran across these in a store and bought a few. They are so funny! Everyone who sees them gets a kick out of them. And they do the job too! Two of them are pocket size and the other a larger tin (with handy rolling instructions) 
I decided to get them wholesale and sell them on ebay because they are just so much fun. Thought you might want to check them out:
