Sakura Pigma Micron 01
The first disposable technical pen to use archival ink, the Micron is favoured by artists worldwide. The high quality ink is acid-free, chemically stable, waterproof, and fade resistant. No smears, feathers, or bleed, through on most papers. The strong plastic tip is steel clad for strength and the small nib size gives you the ability to add some fine details to your work.
