Candles for outdoor and indoor events. All chimney lamps are 2- 5/8" diameter and include an oil reservoir that hangs from the glass chimney. When used with smokeless odorless liquid paraffin and lit with only 1/8" of wicking h, shown out of the tubing, these lamps are VERY safe. Liquid paraffin is NOT flammable without a wick. If they break or tip over the flame goes out immediately, They will not explode, they are much safer and cleaner than wax. The enclosed flame will stay lit at any outdoor event or banquet room. Great gift for someone to add to their home decor. Chimney and oil reservoir are included. The set includes a 10", 8" and 6" high chimneys.
