The Sign Pen by Pentel is one of the bestselling water-based pens, loved worldwide. Born in 1963 as the world's first cotton-core water-based pen, it combines the writing feel of both pen and brush with a smooth acrylic fiber tip that writes easily without bleed-through. This iconic pen became famous throughout the United States after reaching the hands of President Johnson and was even taken aboard a NASA spacecraft.
The hexagonal barrel design and cap-style closure have remained virtually unchanged to the present day, used by a wide range of users for schedule management, to-do lists, idea brainstorming, and rough design creation. The 0.8mm line width produces clear, consistent marks, and the pen is made with 83% recycled plastic content.
