The rulers are constructed from sturdy plastic giving them shatter proof qualities. Essential when used in areas with hard surfaces such as work sites and at school. The rulers feature cm, mm and inch markings.
The ruler is available in 8 solid colours White, Black, Red, Yellow, Orange, Light Blue, Lime Green, Pink and also clear/transparent.
Is a great learning aid at School, College and University as well as an essential stationary item at work and in the office. They are also a great aid for reading or working on documents, I always find with a block colour ruler they allow you to read line by line without losing where you are.
Dimensions are based on the size of the actual ruler not the measurements on it.
