Espacio Arrayán

Place 3 or 4 drops of your favourite essential oil (or perfume) inside the necklace, wait a few minutes until the oil/perfume is absorbed, after that, it is ready to be worn. Your essential oil/perfume will absorb into the clay and diffuse naturally.
If you want to change the oil/perfume that is on the diffuser, wait until most of the original scent has evaporated away (usually 2 or 3 days).
