Our taper candles are a classic and tradional candle color suited for the home, weddings and all occasions. The 18" taper candle burns approximately for 15 hours. The outer core of this taper is made of an extremely hard-shell wax crafted with the highest quality paraffin wax and all cotton wick that prevents the candle from dripping. Tapers fit any standard taper holder. Keep wick trimmed to 1/4". Keep away from drafts.
