Numbered edition WE AROMATHERAPY DELTA recently developed an innovative new Writing Instrument Collection at their “Idea Laboratory” in Naples Italy. The result is the unprecedented LUCKY AROMATHERAPY Writing Instrument Collection. These pens feature a special vase INSIDE the specially designed clip!! The clip-vase holds special oil selected for its ability to offer a sense of well-being upon application to the skin!!! Delta includes a 10ml vial of essential oil with every pen in the collection. To access the Lucky Oil clip-vase, simply unscrew a sphere at the top of the clip. The sphere is attached to a special wooden wand (replacements available). The Lucky oil-wand must be “charged” by immersing it in essential oil for approximately 20 minutes. Once the wand is saturated, the beneficial aroma will last about 2 weeks. Aromatherapy R (energy) Color / sense: energy (soil). Writing instruments are hand-turned from solid bars of special resin. All trim is precious and/or enriched metals.
