Capture the art and charm of beautiful handwriting with a very cherished and unique form of expression, calligraphy. Featuring a nib that consists of two parallel plates, Pilot's Parallel Pens are a major breakthrough in calligraphy pen design that allows the experienced, or novice writer to produce crisp, smooth flowing lines. If it's too difficult to choose just one ink color, gently blend the ink of two Parallel Pen nibs together to create mixable inks with remarkable color effects. Load two pens, each with a different but compatible color of cartridge. Hold one pen vertically and touch the second pen to the first pen for a few seconds. Begin to write with the first pen and delight in the blending of the two colors. Each set comes with a Parallel Pen, one black and one red ink cartridge, a converter to properly flush the pen, nib cleaner and use & care guide. Parallel Pens are available in six nib widths: 1.5mm, 2.4mm, 3.0mm, 3.8mm, 4.5mm and 6.0mm. This pack contains all 6 nib widths. Assorted colors. 6 pack.
