Uni-Ball PIN 0.4(S) Drawing Pen - Black 12-pack PIN-04-BLK The Uni-Ball PIN 04 12-pack provides artists, illustrators, architects and designers with versatile fine-line pens for drawing, writing and technical work. Each pen features a calibrated 0.4 mm tip that produces a clear, defined black line, while Uni-ball Super Ink offers water-resistant and fade-resistant performance once dry. Defined 0.4 mm Lines The calibrated 0.4 mm polyacetal nib provides a visible line while retaining the control expected from a fine-line drawing pen. It is suitable for outlines, technical plans, sketching, annotations, handwriting and detailed illustration. Build Texture, Tone and Definition The controlled tip can be used for stippling, cross-hatching, layering and free shading. Its 0.4 mm line works well for defining shapes, reinforcing contours and adding darker details alongside finer PIN nib sizes. Water-Resistant Pigment Ink Uni-ball Super Ink creates a solid black pigment line with resistance to water and fading once dry. Completed line work can therefore be combined with watercolour and other water-based media without readily disturbing the dried ink. Supported and Protected Tip The polyacetal nib is supported and protected by steel, helping provide control during precise drawing. A removable cap protects the point between uses, while the stainless-steel pocket clip allows the pen to be secured to a sketchbook, notebook or organiser.
