Meanwhile the comparable template ROTRING equal, but also not as expensive, is characterized by the standard graph also made:
+ High quality and design
+ Used from behind, sufficient ink edge
+ Though not really necessary: diameter specifications from both sides readable
+ Very well positioned with the help of precise marks
+ Only about 1.5 mm thick, yet very independent of temperature
Unfortunately, there are those that still exist in the model 315F positioning holes for marking / signs with compass point & Co. the central axes of the circles not more.
Nevertheless, as well as the rotring: Highly recommended if a pencil and paper means something even more :)
