Why the 0.1mm is a Blackbook Essential
Hyper-Detail: Perfect for the "inner-city" details of your sketches—think tiny cracks in 3D effects, fine shading, or micro-patterns inside your letters.
Technical Excellence: The metal-encased fiber tip is built to provide a consistent, skip-free line, even at this microscopic width.
Permanent Ink: Despite the thinness of the line, the ink remains deep black and lightfast, so your most delicate work won't fade or "gray out" over time.
Layering Mastery: It’s the ideal tool to use over the top of dried alcohol markers or paint to add that final layer of razor-sharp definition.
