Board Marker that gives you a peace of mind in the area of performance so that you can focus on making effective presentations Superior technical design prevents premature colour fading and ink drain-back, even if accidentally kept in a vertical (nose-up) position. Brilliant high-intensity inks for vivid, clear and crisp presentations. Soft-feel yet wear-resistant acrylic fibre tip that lasts longer. Markings can be left un-erased on White Boards for several days without the fear of leaving stains behind. On-board markers can be used conveniently on White Boards and Flip Charts.
