Our new Sparkle Skull Earring Kit is to DIY for. An eerily-enchanting sparkling black acrylic was used to create the 2 pieces of each sparkle Skull Earring design. Create spellbinding Halloween perfection with just the right amount amount of shine. Sterling silver jump rings are used to allow the earrings to freely dangle. When finished, these sparkle skull earrings measure 1.25 inches (Not including your sterling silver ear wire).
