Crossbow Plain Coloured Reading Ruler

This version of the ever popular reading ruler provides a larger reading area, suitable for working with diagrams or maths problems. In addition, the surface finish of these rulers is glossy on the front and matt on the back to provide improved usability over a range lighting conditions.

The reading ruler is a flexible transparent coloured plastic strip (205mm x 74mm) overprinted with two tracking lines. It thus combines the glare reduction benefit of reading through a coloured overlay with the guidance of a ruled line to assist tracking.
