The
aromatherapy
diffuser is composed of four
individual pieces. These pieces included the top and bottom
outer colored shells, the gold vent cap and 0.02 oz. glass
vial. The glass vial could possibly be filled with herbs, potpourri,
or with essential oil soaked cotton. Once the vial is
filled the gold colored vent cap is screwed onto the glass
vial, the glass vial slides snuggly into the bottom half of
the colored shell, and the top half of the colored shell slides
smoothly over the gold vent cap. Unlike the sealed compartment
aromatherapy diffusers, the four-part diffuser can be reused
simply by washing out the glass vial.
