Pigma Micron Pen : Black : .20mm Size 005
These thin ink pens are great for making permanent markings on wood, paper, cardboard, fabrics and many other materials.
The Pigma Micron ink will not feather or bleed through the thinnest papers, and is smear-proof once it has dried.
Please note : it is always a great idea to test marking tools in manner & surface intended each time.
