Enjoy a wonderful fragrance over and over again, thanks to the Bolsius Scented Candle Clean Light Starter Kit! This holder is made of double-walled glass and suitable for refill scented candles. Once the scented candle has burned out, you can put a new scented candle in the holder. Because the refill burns up completely to the last drop of wax, you won't have any waste left in the candle! So, friendly to the wallet and the planet.
