Candle by the Hour beeswax candle is easy to use and lasts hours upon hours. Merely place the beeswax coil through the spring loaded clip in desired increments. Three inches of candle wax will burn approximately one hour. Once the candle burns to the clamp, it will extinguish itself. Also the beeswax will not drip, but evaporate. Please still follow the golden rule and never leave a burning candle unattended.
