Rattan essential oil keychain diffuser How to: Add your favorite essential oils to the wood bead to begin diffusing your oils! Avoid getting oils on your cotton tassel, it will stain the tassel. Clip your essential oil diffuser on your keys, purse or backpack to enjoy the aroma of oils. Please note: all designs are handcrafted and one of a kind. Not one rattan piece looks like a twin, they are all uniquely handcrafted. Color of rattan + size will vary!
