For the use of standard cotton wicks, always trim wicks to 1/4″ before use. Always keep candles free of any foreign objects including flammable items, books, blinds, curtains, clothing. Only use candles on even flame resistant surfaces. Upon using candles, never allow burning for more than 4 fours at a time. Candles should not be used after 1/4″ wick remains. Only use candles when supervision and NEVER leave a burning candle unsupervised. Keep burning candles away from air currents such as ceiling fans and drafts.
