A cat rendered in Celtic style decorates this diffuser. All of our lead-free pewter diffusers come on a 24" rhodium chain. They come with six replaceable diffuser pads. Place a drop or two of your favorite oil or fragrance on the pad and place it inside the diffuser. Youll smell great all day when you wear the diffuser as a necklace, or you can hang it as an air freshener. This diffuser is 1-1/2" long and 7/8" wide.
