A 12-pen set of black micro fineliners with nylon nibs and a brush tip. Archival, quick-drying ink becomes water-resistant once fully dry.
Crisp, consistent lines – thanks to high-quality nylon nibs
Nylon nibs are supplied across a range of sizes, from 0.2mm to 3.0mm, plus a brush tip, maintaining steady ink flow and resisting skipping. Extra-fine tips require light pressure to protect the point.
Consistent line quality helps with technical drawing, precise hatching and fine lettering, improving control on paper, vellum and trace.
Waterproof, archival ink – with pigment-based formulation
Archival pigment ink dries quickly and becomes water-resistant when fully dry; labelled acid-free, fade resistant, photo safe and conforming to ASTM D-4236 and EN71-3. The ink is non-toxic and odourless.
Finished work stands up to light exposure and light water contact once dry, making the ink suitable for long-lasting sketches and layered techniques.
Versatile mixed-media compatibility – with paper and paint-friendly ink
Ink compatibility is specified for use with pencil, watercolour, alcohol markers and highlighters, and nib construction supports tracing and sketching on various surfaces. A brush tip adds flexibility for stroke variation.
Pairing these pens with pencil underdrawings and watercolour washes is straightforward, giving reliable outlines and inking for mixed-media projects.
