Four pomanders. Part of a group that I sold a few years ago to a new age store named Inspired, now sadly out of business. The smallest is about one inch high. Each has an interior chamber carved out through the holes and filled with cotton to be saturated with a perfume or essential oil.
Left to Right: Unknown wood, Antler with a bone bead, Walnut wood, Driftwood. The walnut one has a fill hole at the top with a removable plug that is connected to the main body by a cord with a bone bead on it.
