The Pilot Iro-Utsushi is a dip-style pen designed for use with fountain pen ink, allowing you to write by dipping its nib into the ink. Unlike a traditional dip pen, it features a tip with a fountain pen-like point, offering a smooth, gentle touch on paper, perfect for fine writing and illustrations. A wavy line is engraved on the tip, providing a clear visual guide for where to dip the pen into the ink.
