This is our first candle out of a mold. We find skulls to be as classic as it comes, and can stand equally for science and horror. This is definitely like a sculpture and would make a great display piece. Our first unscented paraffin candle is a long lasting, very solid wax that burns very clean. * The burn lasted over ten hours for us. * 4 colors: black, white, aquamarine and orange. * Measures 3 x 3 3/4" *As with all candles, one needs to stay in the room where this is burning. The flame should be extinguished every 3-4 hours. **Trimming the wick is super important with this one-- it will burn too high over time. Contact me any time with questions.
