Enjoy a delightful scent over and over again with the Bolsius Clean Light Scented Candle Starter Kit! This holder is made of double-walled glass and suitable for refill scented candles. Once the scented candle is burned out, you can insert a new scented candle into the holder. Because the refill burns completely to the last drop of wax, you won't have any waste left in the candle! Friendly to both your wallet and the planet.
