These small beeswax skull candles are great for using in spells. They can be used as a focal point for many types of spell casting from using them to represent your connection to your beloved dead on and ancestral altar. Representing a target during a hexing spell or ritual. You could even use them for healing magic after all then trying to get a lock on a person instead of using a traditional poppet, why not use a green skull (we as humans all have skulls after all.)
*Please note that while burning these candles, the wax will spill over, so you will need to burn them on a dish or in a jar.
