The versatililty and uniqueness of this marker sets it apart: First-Due to its oblong design, it won't roll down drafting, design, or shipping receiving tables that have inclines. It's less likely to roll off a dashboard or other vehicle interior surface. And you get all the reliability and longevity of Sharpie, the leader in utility markers. The ink is specially designed to be resistant to fading- better for your more critical archiving projects.
