Flippins were created out of frustration with cleaning out my wax warmers/burners/melters. I found that cleaning out the scented wax was time consuming, messy and sometimes lead to breaking the trays. I tried all the tricks to getting the wax out but there had to be something simpler. And there was, I created the Flippin to line the trays and I was Flippin' Happy with the results. I could easily switch out my waxes with the Flippin, dispose of it and replace with a new one. P.S. The flippin with the old wax is a great firestarter for the campfires, fireplaces and wood stoves.
