Precision fineliner with metal-tipped nib, recommended for technical and freehand drawing on light-colored paper, contouring, and working with templates. The pigment-based, water-based ink is waterproof and extremely lightfast after drying. Line width: 0.25 mm. Thanks to the practical clip on the cap, the pen cannot roll away and can be clipped into a pocket or onto the cover of a sketchbook.
