CAUTION: Before
refilling glass holders with new candles clean it well so there's no remaining wax and / or wick from the previous candles, place new candle in the middle of the glass - Place your candles on a flat surface - If multiple candles holders are lit keep them apart, putting them too close to each other can cause the casting to be too heated posing a safety hazard - Always keep out of reach of children pets and away from flammable materials.
