This "Bleeding Skull" Pillar Candle is made using 3.6 - 10.1 ounces of a paraffin wax blend. We have 2 sizes (Regular and Small). The reason they are called the "Bleeding skull" is because as it melts, it will "bleed" red wax. Kehau has a myriad of scents and colors that she uses when making any of her candles. There can also be up to 1-3 mystery "gifts" that will be found in this candle as the wax melts. The gifts are of the oddity type: bones, bone beads, crystals, owl pellets, horn beads, teeth, claws, stones, & charms.
