This pillar measures 3″ in diameter by 9″ tall. It is the tallest of the three shown here. The sides are completely smooth. The wick is 100% cotton. This pillar looks really awesome anywhere in your home you desire the soft, warm glow of candlelight. The burn time is approximately 90-100 hrs. For a very tall candle like this you may need to carve the wax from the edges and “feed” it back in the center, so that the flame can continue to be seen!
