Sharpie
"Sharpie" was originally a name designating a permanent marker launched in 1964 by the Sanford Ink Company (established in 1857). The Sharpie also became the first pen-style permanent marker.
Today, Sharpie stands for far more than just markers. Made to write on, stand out on, and stay on practically any surface, it’s The Permanent Marker born for unique, unruly, courageous, outrageous self-expression that never, ever fades from glory.
