The Orbis Nox Eros diffuser comes with a natural, dark beechwood, spherical base and a hand-blown glass bottle. Unlike most other diffusers, the Orbis Nox Eros 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.
