Berol Colourbroad Pens are a classroom favourite that help children confidently express their creative side for endless colouring and writing fun.

• Filled with vivid, washable ink. 
• Washable ink can be washed off most clothing and removed from most porous surfaces.
• Transparent ink which allows additional colours to be created with overlays of the brighter colours.
• Smooth, steady ink flow for consistent, easy-to-see lines.
• 2 Week Cap Off Life - all colours except for blue and black, can be left uncapped for at least 14 days before they dry out.
• Durable broad tip provides excellent coverage over large areas.
• 1.2mm line width.
• Contains 24 pens in each of the 12 colours: black, blue, light blue, brown, green, light green, grey, orange, pink, purple, red and yellow

The specification for the broad marker lists 1.1mm-1.7mm as the allowable line width range - the line width will vary through usage due to multiple factors relating to the shape and firmness or the nib as well as writing angle.
