The Pigma Micron is a long-lasting marker pen (non-refillable) with a hard fiber point suitable for writing or drawing.
The pigmented ink in these pens is permanent, lightfast, waterproof and fast-drying. It will not bleed on most artists' papers. These pens are highly useful for studio or field work, and work especially well for drawings which will receive watercolor washes.
The 3-pen set includes .01, .03 and .05 nibs.
