A stylish black candle made that has been treated with fire. Reusable with spare inserts (sold separately). Standard Volcano candle comes with spearmint essential oil beeswax candle insert. The Volcano series from WOOD MOOD is a hot interior decoration. Each candle undergoes "consecration" through the flame. The wood is then cleaned of ash and treated with wax in order not to leave dirty marks from the touch. The bottom of each candle has a special cork layer to protect the furniture from scratches. They wonderfully decorate the space independently and in compositions.
