To get the best use of ALL YOUR CANDLES letting them burn for only 1 hour at a time then putting them out you will notice they last a lot longer. Use in any nonflammable, heat-resistant, well-ventillated container. Keep burning candle within sight. Keep out of reach of children and pets. Never burn candle on or near anything that can catch fire. Never move candle while burning or while wax is in liquid state. Discontinue use when 1/2" of wax ramains to prevent heat damage to surface!
