This high quality sleek aromatherapy diffuser (available in 3 colors) could be a great addition to any purse or bag. It's a convenient compact way to take aromatherapy on the go. The aromatherapy diffuser is composed of four individual pieces, the top and bottom outer colored shells, the gold vent cap and the 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. The four-part diffuser can be reused simply by washing out the glass vial. Size: About 3" Long x 1/2" Diam. Comes with a lavender sample and complete instructions.
