Itoya Nikko Waterbased 3-Pen Set

These fine-point pens are the same as the Itoya Nikko Permanent Pens, but with a non-waterproof ink. They write on virtually any surface, including film, metal, plastic, glass, wood, and cellophane. Each pen contains a generous supply of a fast-drying, non-waterproof black ink that is dense and suitable for reproduction purposes.

The tips are fitted into long metal sleeves to allow drawing close alongside templates and rulers. They're perfect for detail work, since the hard plastic porous tips won't fray, and every line is precise.
