A calligraphy set we are proud to offer. The Rotring ArtPen turns fine penmanship into art. Three precise, stainless steel nibs in 1.5, 1.9 and 2.3mm sizes are delivered with your ArtPen. Three caps, with handy nib-size labels, also arrive. These individual caps allow you to seal your nib and ink feed when not in use. You will also receive a starter box of black ink cartridges. Our own Colorado Pen standard cartridge fits perfectly and is available in a wide range of colors. An ink converter is not included, but may be purchased separately.
