NOMOS pencils are produced for NOMOS Glashütte in Budweis, Czech Republic—so in our extended neighborhood: Koh-i-Noor has manufactured pencils for the world since the 18th century, and so it knows as much about them as we do about constructing fine watches. Replacement leads, if needed, are available in stationery shops. And if you unscrew the cap, you have the sharpener.
Metal mechanical pencil, lacquered. 11cm long, the push button on the end dispenses sharpened lead. The hardness of the lead is HB with a diameter of 0.2cm.
