Refill leads Pica 4020SB — water-soluble graphite leads set (4 graphite, 2 red, 2 yellow) for pencil 3030

Set of replacement leads Pica 4020SB for pencil model 3030 contains water-soluble graphite inserts in a mix of colours: four graphite, two red and two yellow. These refill leads are intended for the Pica 3030 pencil and provide temporary, water-erasable marks on a variety of surfaces. The water-soluble graphite formulation allows clear, contrasty marking that can be removed with water or during washing, making the set suitable for tasks that require non-permanent lines.

Advantages

The leads offer consistent line quality and smooth application thanks to the graphite composition. Colour variety—graphite, red and yellow—improves visibility on different materials and helps with colour-coding. Water solubility enables easy removal of marks where temporary layout or pattern lines are needed. The refills are sized for quick replacement in the compatible pencil, reducing downtime on job sites or in workshops.

• Construction layout and temporary marking on wood, drywall and other building materials
• Tailoring and pattern marking on textiles where temporary lines are required
• General-purpose workshop marking and colour-coded annotations

How to use

Insert a refill lead into the Pica 3030 pencil according to the pencil’s replacement procedure. Mark the work surface with light to moderate pressure to create visible lines; heavier pressure will produce darker, thicker marks. To remove marks, apply water and rub gently with a cloth or sponge; for fabrics, follow fabric care instructions and test on a small area first. Store unused leads in a dry place away from direct heat to preserve integrity.

Usage recommendations

Use the coloured leads to improve contrast on different materials and to separate temporary layout lines from permanent notations. For delicate fabrics or finished surfaces, test the lead and removal method on a hidden area before proceeding. Replace leads promptly when worn to maintain consistent marking performance.
