Super ruler Linex-S50MM

Linex’s legendary super ruler uses a unique patented anti-slip principle, which makes it far more effective and easier to use than a traditional ruler. An integrated rubber strip prevents the ruler from slipping on surfaces. The ruler can easily be repositioned by tilting it. Graduated in mm with a 0-50 cm scale on one side and a 25-0-25 cm scale on the other. With two bevels and two rubber strips.
Material: transparent acrylic with green centre section. The ruler shown in the picture is 40 cm.
