Concrete Drill Bit Candles feature the special flutes found on the top of their namesake bits. On the originals, they’re designed to clear away dust. Ours may not do that for you, but they provide a much nicer ambiance in your home. This candle is dripless but allow for maybe one or two. Made from a blend of Soy and Beeswax. Fits in a standard 7/8" (22mm) candle holder.
