The Sharpie Liquid Pencil has gotten me officially excited for the upcoming school year. This pencil uses liquid graphite as ink. The liquid graphite is erasable for up to three days, becoming permanent thereafter.
Think of all the paper you could save by using the Sharpie Liquid Pencil. You could use one notebook for the whole entire semester! This liquid pencil looks awesome and I can't wait to get my hands on one this fall.
