Rotring precision templates are robust and non-warping, with perfectly formed, true-to-standards symbols selected for the most varied applications.
The transparent, yellow-tinted material leaves even the finest of lines (e. g. ones drawn with a Rotring fine-lead pencil) clearly visible through the template.
Circles of 1-36 mm dia. in 1 mm increments. With polygon guides and protractor. Radii 6, 10, 16, 20 mm. With millimeter ruler and finger-lift.
