In the pencil lead fragrance is encapsulated using nanotechnology. Microscopic bubbles containing the fragrance are blended in with the lead. When the pencil is used to write, the fresh fragrance pops out of those tiny nanocapsules, filling the room with sweetness and enlightenment. The manufacturer says the fragrances are shelf-stable for three years unopened, two years in the plastic case and three months out in the open. The manufacturer says the fragrance gives aromatherapy. The idea is to use the term “aromatherapy,” and then build an entire industry around it. It just sounds so effective and soothing. But whether these pencil leads actually have any therapeutic value or not, it might be a pleasure to have a pleasant scent surrounding about as you write. The manufacturer is Ain Supplio whose pencil lead from Pentel uses nanotechnology to release allegedly mind-expanding aromas, letting you smell your way to smartness while you scribble your thought on a piece of paper. The pencil leads are sold in three different scents, Refresh, Healing and Positive, which aromatherapists say can deeply sooth the person.
