For those who like the ink of a traditional Micron, but worry about breaking the tip, here's a great solution with their plastic nib pen. It's the same archival quality pigment ink with a durable polyacetal nib structure providing skip-free writing. Depending on the amount of pressure, you can produce a 0.4mm-0.5mm line. Fade resistant, waterproof, and chemical resistant, the quick-drying pH neutral ink does not bleed through most papers and won't smear or feather when dry.
Capped barrel measures 5 5/16" long, 3/8" in diameter. Cap has a metal clip. Ideal for use on paper. Made in Japan. Not refillable.
