This range of candles from Heaven Scent is made from plant wax, not paraffin. The wicks are of cotton, any glass used is from a recycled source, and the fragrances are from essential oils. We liked the subtle perfume that these gave the candle. We reviewed the Limeleaf and Ginger candle, and it had exotic undertones without being overpowering. It is a lovely green colour, which seems to glow when lit. Approximately 50 burning hours.
