Keep candles out of reach of pets, children, or flammable items when lit. Keep burning candles on a heat-resistant surface as the bottom can get very hot. Never leave a burning candle unattended.
To always have an even top, allow candle to burn until the top layer of wax is able to pool completely to the edges of the jar - about 2 hours. This prevents the tunnel-ing effect of the wax.
Always keep the wick trimmed to 1/4".
Keep your candle stored out of direct sunlight to prevent the wax from melting and deforming.
