2 in 1 wax warmers are a type of wax warmer that can be used to melt both wax melts and candles. They consist of a base that can hold either a candle or a dish for wax melts, as well as a heating element that melts the wax and releases its fragrance into the air. One of the benefits of 2 in 1 wax warmers is that they offer the flexibility to use both wax melts and candles, depending on your preference.
