These Agnes&Cat  Jam Jar Candles - Moonstone are presented in nice recycled glass jars (220 ml) that can be reused once your candle has burned out.
Soy wax is a perfect eco-friendly alternative. It is so much cleaner and burn longer. A little more expensive but worth it. Soybean Jar Candles throw scent beautifully and leave a minimal wax residue. These 100% all-natural candles produce 95% less soot too, they are vegan friendly and not tested on animals.
