The Pilot Parallel Pen represents a major breakthrough in calligraphy pen design! The pen nib consists of two parallel plates, allowing the writer to produce lines sharper than existing calligraphy pens. You can create blended color lines with its special mixable ink as well. (Calligraphy artwork kindly provided by JetPens customer Josh Scruggs.) Four nib widths are available for your writing needs: 1.5 mm, 2.4 mm, 3.8 mm and 6.0 mm.The name "calligraphy" comes from the Greek words for "beautiful" (calli) and "writing way" (graphy). Capture the charm of beautiful handwriting with this very cherished and unique form of expression!
