If you’re looking for the best essential oil diffusers but find the plug-in varieties too overwhelming, then the Roy Aroma Vent Clip Lockets provide an excellent and very cute alternative! In this package you get two lockets with two different designs: a sunflower and tree of life. The pack comes with 12 different colored pads that act like little sponges to absorb your favorite essential oils. To relieve stress and keep alert while driving, choose a relevant oil for the pads, add a few drops, place them into the lockets and then simply clip onto your air-conditioning vents. What we like about these little lockets is that they’re great for the home and office too.
