I see this as a winner! I believe the comment that preceeds mine is a key to your gold mine! You can slightly change the design or the marketing toward other items that may be hard to clean...such as computer keyboards!!!! What I think is Ironic is what is the two things that usually cause our keyboards to gunk up...soda and coffee!

I'm curious on how much you plan on selling this for. Also, you can market your colors to colleges and sport lovers!

May you have Great Fortune!
