Kristal candles are new patent protected palm wax tapers that are completely clear. No two are the same because of the unique way the air bubbles inside of them.
These clear candles might make a nice change from gel candles because gel can only be used in containers. It would also be fun to put embeds inside of these and make them a little thicker.
Each taper candle will burn for more than 12 hours and apparently have little to no dripping or soot. For more information on clear crystal candles, see Wayfarer Candle Company.
