The Faber-Castell connector pens are ideal for drawing on card, paper, posters and more. Featuring a unique design which allows you to click the pens together, the ink is non-toxic, water-based and capable of creating bold and crisp lines. With a unique and child-safe cap that is designed to prevent the ink within from drying out, there is more creativity to be had with this pack of 10 pens that goes beyond ink and colour.
