These tall opium 3 x 12 pillar candles will add height to you candle arrangements without the need for a raised holder. Burning these scented candles will add a relaxing ambiance to the room as well as make it smell lovely. Always burn pillars on a candle holder or heat resistant surface to avoid damage to your table when the flame gets to the bottom. These tall candles are made out of paraffin wax and have a cotton fiber wick. Burn the candle long enough for the liquid pool to to almost reach the edge then extinguish the flame. Allow the wax to cool before relighting it again. Doing this will maximize the length of time your candle will burn and allow it to use up nearly all the wax.
