Melts are made of soy wax, which is biodegradable. Each 2.5 oz melt wax has a melt time of 30 hours. Classic Wax Fragrances contain both fine fragrances and natural ingredients. Our soy wax holds a high fragrance load and is proudly poured in the USA! Wax melts offer a no flame, no soot, no smoke sensory experience. Pair with one of our Candle Warmers Etc. Fragrance Warmers, available in a variety of styles and colors. 2.5 oz of wax is poured into a plastic tray that divides wax into 6 cubes. Tray can be used for wax-cooling and remelting your wax later!
