This curved ruler from Prym has a flexible metal core which makes it an indispensable utensil for measuring, marking and transferring rounded and curving shapes. A flexible core inside the ruler makes it possible to shape the ruler as you require and then to straighten it out completely again later on. It can be placed without problem on narrow curves, in order to transfer the shape onto paper or fabric.
The flexible curved ruler has a scale in centimetres on one side and a scale in inches 50 cm/20 inches in length.
