OHTO Graphic Liner Needle Point rollerball drawing pens produce the same fine and consistent lines as fiber-tipped drawing pens but with a sturdy metal rollerball tip instead! This means that you'll be able to use every last drop of the waterproof, lightfast, archival-safe pigment ink without having to worry out about wearing out the pen tip over time.
This set comes in a plastic pouch with a slider zip closure and contains six pens of varying tip sizes: 005 (0.3 mm), 01 (0.4 mm), 02 (0.5 mm), 03 (0.7 mm), 05 (1.0 mm), and 10 (1.5 mm).
