The Incognito Legrand Platinum Ballpoint pen is a twist-action ball pen. It is produced in a limited edition of 250 pieces, with each pen individually numbered and hallmarked .999 Platinum-plated. Layers of pure platinum (.999 Platinum) have been applied 10 times over the solid brass barrel, which features a rare diamond-cut engraved pattern. Each time the layer of platinum is applied it is followed by the application of a thin layer of clear coating and then finished by the use of careful manual polishing. Medium point, German-made ball refill provides smooth, skip-free writing. Original ballpoint refill is selectively interchangeable with a variety of commercially available ballpoint pen refills including Montblanc and Parker.
