Reusable: We wanted to make sure that in addition to a candle, you were getting a high-quality piece of pottery. When you finish these candles, you can simply remove the wick and its metal holder, and then heat the cup with a blow dryer or put it in the microwave for 1 minute on a paper towel. While the wax is still hot, safely use a paper towel or rag to wipe off the remaining wax, and then put it in the dishwasher. This shape is a perfect juice cup or storage container.
