The anniversary rulers have arrived :)

Still cold from the courier van, straight from customs clearance, and already on fb. Phew, they arrived on time. A quick check to see if everything turned out well. Although the rulers won't work as electronic devices, the stress of quality testing is just the same.

The manufacturing technology is identical to that of the PCB boards used in our electronic devices. But these are special – for the first time, black lacquer on the laminate and copper covered with real gold. The rulers feature scales in cm (0-20) and inches (0-5), diameter measurement ranging from 0,2 to 3 mm, protractor and compass functions, a times table and a cheat sheet of basic geometric formulas.

Special rulers for those who love learning :)
