These Faber-Castell Connector Pens feature a large tip that provides bold lines so your writing will be visible from throughout the room. Each marker contains a clip on the lid so you can connect your markers together in your school pencil case and keep them all organised. Each marker has a 3 mm bullet tip which provides a wide line. They’re perfect for use in meeting rooms or classrooms where you need to write on a whiteboard and ensure your markings are seen. The water-based ink produces vibrant colours and can be easily removed with a whiteboard eraser or dry cloth. You can clip these markers together, making it easy to store them. You don’t have to worry about your markers drying out if you accidentally leave the cap off for up to 24 hours. There are 24 markers in this pack, in assorted colours.
