Uni-Pin Coloured Sketching Set — Pack of 8

The Uni-Ball Pin is already one of the most trusted drawing pens available — a fineliner with steel-reinforced tip, fade-proof and water-resistant Super Ink, and a range of nib sizes that makes it the first choice for illustrators, architects, and urban sketchers the world over. This eight-pen Coloured Sketching Set brings a different dimension to the Pin range — not a set of bright colours, but a carefully chosen palette of tonal drawing colours that extend the expressive range of monochrome ink work without straying from the naturalistic, controlled quality of line that the Pin is known for. The set contains eight pens across four tones — Black, Sepia, Light Grey, and Dark Grey — each available in two formats: a firm brush tip for expressive, variable-width marks and broader strokes, and a 0.5mm fine nib for controlled, precise line work. The result is a self-contained sketching kit that covers the full range of marks a tonal drawing demands — from the darkest shadow lines in black to the most delicate mid-tone washes suggested by light grey — in the same pen family, with the same ink behaviour throughout. The tonal range is inspired by traditional artist sketchbooks and is particularly well suited to figure drawing, portrait sketching, architectural and urban sketching, and any working method where a warm sepia tone or cool grey adds depth and nuance beyond what black alone can achieve. Because all four colours use the same Super Ink formulation, they are water-resistant once dry — watercolour washes can be applied over dried ink marks without smearing or lifting, making this set an ideal companion for mixed ink and watercolour working. Contents: 4 brush tip pens (Black, Sepia, Light Grey, Dark Grey) and 4 x 0.5mm fine nib pens (Black, Sepia, Light Grey, Dark Grey). Why four tones rather than bright colours? The four tones — Black, Sepia, Light Grey, and Dark Grey — are the colours of traditional monochrome and limited-palette drawing. Used together they give the full tonal range of a drawing without introducing colour, allowing tone, light, and shadow to be the primary expressive tools. Sepia adds warmth that pure black cannot, and the two greys allow subtle mid-tone work that lifts the drawing beyond the flat contrast of black and white alone. What is the difference between the brush tip and the 0.5mm nib? The brush tip is firm and responsive to pressure and angle — at light pressure it produces a fine line; with more pressure and a flatter angle it produces a broader, more expressive stroke. The 0.5mm fine nib produces a consistent, controlled line regardless of pressure, suited to detail work, cross-hatching, and technical line drawing. Is the ink waterproof? Yes — all eight pens use Uni-Ball's Super Ink formulation, which is water-resistant once fully dry. Watercolour washes can be applied over dried marks without lifting or smearing, making these pens particularly useful for ink and watercolour mixed media work. Can the brush tip pens be used for brush lettering? Yes — the firm brush tip responds well to the pressure variation needed for brush lettering, producing thick downstrokes and fine upstrokes when used with appropriate technique.
