The Pilot Parallel calligraphy pen features a unique nib comprised of two parallel metal plates. This allows it to distribute ink more evenly than conventional metal italic nibs while also being crisper and far more durable than a felt-tipped calligraphy pen. Its special, mixable ink allows you to create beautiful color blendings and gradations by touching the nibs of two Pilot Parallel pens together. We recommend you to try all four sizes of the Pilot Parallel: 1.5 mm, 2.4 mm, 3.8 mm and 6.0 mm. With all four pens in your calligraphy arsenal, you'll be prepared for every possibility. The smaller sizes are great for adding style to regular writing, while the larger nibs are perfect for bolder uses like titles or greeting cards. You can even use them together in a single project to create additional contrast. Pilot makes exceptional writing instruments to suit all your needs. We have fountain, ballpoint, retractable, erasable & gel ink pens, whiteboard markers & more for every writing style.
