This magnetic whiteboard ruler holds against the whiteboard while ruling lines making it the perfect whiteboard accessory for the classroom or office. A professional looking ruler (1000 x 60 x 10mm) with magnetic backing for whiteboard use. It's very strong and is made from extruded plastic.

By having a different layout than normal with centimetres printed on the top of the ruler and millimetres on the bottom, enables children to clearly see the distinction between centimetres and millimetres.
