For the best results with Sand Wax (burning sand), it's important to use a heat-resistant container that matches the candle's size. Ensure the wick protrudes approximately 1 cm above the wax for an even burn. If you're using multiple wicks in one holder, maintain a minimum distance of 7 cm between them for an optimal burning experience. Has the wick burned down? Simply replace it and immediately enjoy the atmospheric candlelight again. Wax remnants can be reused by turning them over and relighting them. The wax is odorless, allowing you to choose which fragrance oil you want to add to the candle for a personalized scent experience. Bag of 10 wicks of 7 cm - 24-30 burning hours
