These pens boast a rich and bold water-based colour and are odourless, acid-free, and quick-drying. Each pen is labelled with a colour number, and the shape of the barrel ensures your pens won’t roll off the table while you’re working. The superfine tips are ideal for the most intricate tasks. They are encased in metal which makes them very durable and also ensures that the tips won’t bend or break. They’re the ideal choice for detailing with rulers and stencils, drawing, sketching, cartooning, and journaling. This set comes in a metal storage case that will keep your pens safe, organised, and perfectly packaged for travel.
