Our oil candles are made with a special glass holder for a fiberglass wick. Fiberglass wicks do not get consumed so they are useful for the life of the product. Adjust wick to desired length, our oil candles use a purified liquid paraffin wax so it will burn just like a candle. Each candle stands approximately 4 1/2 inches tall and is approximately 4 inches in diameter. This is a handmade product so variations do occur. Comes with oil candle, wick, wick holder, funnel, and instructions for use. Never burn unattended. Paraffin oil is available online.
