The Orbis Nox Vitis diffuser comes with a natural, light beechwood, spherical base and a hand-blown glass bottle. Unlike most other diffusers, the Orbis Nox Vitis contains no plastic parts that would corrode when in contact with the oils. With proper care, your diffuser can last for many, many years. ArOmis diffusers use no heat or water to function, keeping the essential oil in its natural state as it becomes a mist.
