Your order comes with 5 Stainless Steel Cotton Wick Thermal Tubes And 5' of 3/16" Turbo Air Core Technology Wick. 3/8" Diameter Hole For Tube needed. Stem length 6/10" Long. Stainless steel holder for oil rock candle, lamp adapter, and mason jar candle. These thermal wick tubes have a variety of uses. Many people make rock candles. I have made a mason jar candle from these by just drilling out a mason jar lid to the diameter of the tube measured at the base. Just add oil and you have an improvised oil candle for mood lighting or emergencies. (18)
