It features Pilot's patented Frixion ink technology, which allows the ink to be erased without any smudging or ghosting. This pen provides a clean writing experience, and the Frixion ink also prevents smudging, fading, and bleed-through on all types of paper. The ink is also designed to be acid-free and water resistant so it lasts longer and is easier to erase. The pen has a comfortable barrel design with a soft grip for easy writing. It also features a retractable clip so it can be easily stored when not in use. It is an ideal choice for a variety of writing tasks such as taking notes, drawing, and more.
