SAKURA Pigma Micron Black Open Stock 03 (0.35mm) Fineliner Pen  (Ink Color - Black)

Pigma ink, invented over 25 years ago, continues to be the most reliable permanent ink on the market today. In the early 80's, our labs identified the need for a drafting tool that used better pigment-based ink instead of low-grade dye inks. The breakthrough came with the discovery of how to reduce the pigment particles to submicron size so that the ink flows evenly through the narrowest of pen nibs. Having such a long history with this specialized ink, We have been able to constantly improve on our formula resulting in the smoothest flow, the most pleasant colors, stable pigments, and practical writing instruments. Pigma has become the standard for what is defined as permanent ink, relied upon by those whose jobs depend on marks and notations that stand the test of time. The properties of Pigma ink create magic on paper for millions of users.
