Cotton, wool, wood beads and natural fibers blend to form these charming tassels that can be used in a multitude of ways:
Zipper pull
Key chain
Tassel
Bowl/tray fill
Essential oil diffuser for car or home
 
To use as a diffuser, simply add a few drops of your favorite essential oil to any part of the tassel and it will absorb and release the scent. The strength and length of diffusion will depend on the oil used. 
 
Designer's choice, but you can pick the general color scheme.
