Berol provide long lasting pens that are designed with a fibre tip to ensure that they will not run dry. Designed for durability, these pens will last for up to 14 days without drying out even if the cap is left off. With water-soluble ink, it is easy to wash out stains in clothing or fabric too. The fine nib of Berol Colourfine pens delivers a crisp 0.6mm line that is ideal for fine illustration or colourful writing tasks.
