These dip pens are a combination of Pilot’s stainless-steel laser cut nibs with the body of a traditional dip pen. The stainless-steel nibs are also rust-free. Iro-Utsushi utilizes the same pen point in the nib that is found in other Pilot fountain pens, offering extreme durability and the nib won’t wear out over time and use like other common dip pens. Pilot’s Iro-Utsushi dip pens are a fantastic way to change and test a variety of ink colors. Simply submerge the nib into your ink of choice up to the designated line that is engraved on the nib, remove the dip pen from the ink, and begin your smooth-writing experience. To switch colors, clean the nib with water and wipe it completely dry. Iro-Utsushi is available in three Resin colors or two Wood color bodies, in either a Fine or Medium nib.
