Seascape Gel Candle - Scented - Real Sand & Shells - 14 oz RoundThese candles are long lasting and smell great. They burn almost twice as long as a paraffin or soy wax candle. The smoke is very minimal. I hand pick and place all the shells, sea stars, sand dollars, etc. The candles are covered and labeled, do have a "Don't leave a burning candle unattended" safety warning on them, and the containers are thick glass, made to sustain high heat. Each candle is filled with 14 oz of gel wax.
