Pentel is a Japanese company that has produced writing instruments for over 50 years. During that time, they've developed the ideas behind two-thirds of the writing instruments in use around the world today, from the first acrylic fibre-tipped pen, to tough permanent markers, to dry-wipe markers for presentations, to no less than 26 shades of pigment gel ink. They're also a pioneer in graphite-lead research: more than four decades of research and development have made their strong and smooth Super Hi-Polymer the top-selling lead in the world.
