Decorative wooden caps or collars for diffuser bottles. These caps sit on the shoulder of the bottle, without screwing on. These caps have a metal ring on the inside to keep the wood cap clean and prevents the diffuser oil from transferring from the reeds to the cap. Makes replacing reeds and oil easy since it never absorbs into the caps. The inside diameter of the cap is 1 3/8" x 1 7/8" tall.

These caps will fit our 3.4 oz apothecary bottles. The will NOT fit the diamond bottles.
