They can be used to protect, or banish someone by inserting a name, doll, or piece of clothing to them and sealing it with wax.
They can be made into candle holders, sensors for your altars, smudging bowls, offering bowls, spell holders, The list goes on. Creativity is everything, and you can find magic everywhere!
