The abalone shell is traditionally used to burn herbs and smudges. A Paelo stick or Sage can be leant against the edge while still alight. (Of course, never leave it unattended).
Environmental info: These abalone shells come from South Africa & Mexico. They are farmed and are not caught in the wild. This means natural habitat is not destroyed and the supply is sustainable.
