A PocketSpa set includes:
1. A mini mist diffuser with batteries
2. An oil of choice
3. Mixer bottle
The PocketSpa operates on four (4) AAA batteries and diffuses a very fine mist making sure we get optimal health benefits from the pure plant-based extract in the essential oil. It has a 2-year replacement warranty.
My personal Epoch Essential Oil lasts for three to six months depending on my consumption.
