This is diffuser is a whole vibe, the base is real concrete/stone, the soft mist flowing out of the diffuser that is filled with your favorite non-toxic home fragrance or wellness scents. A nod to the concrete style that is trending. This is in honor of the best selling diffuser of all time the Young Living Aria Diffuser, although smaller, you will not miss the size (or the price tag) that the YL diffuser comes with. We love having this on in our home, it makes it cozy and doesn't make me miss those toxic filled candles. It's very simple to use, simply lift the lid off add water and oils, put the lid back on and turn it on.
