I think I have what you are looking for. I have a battery operated cheese hat. It stores 2lbs of melted cheese, and holds it warm for apprx. 2hrs. It also comes with a matching cheese bowl for your nachos, or party favours, whatever you may want to put in it.
Anywho, I've been looking to sell this peice of steel for quite some time, I'm lookin for the best offer darlin.
Talk to you, Billy Jo
