Mechanical pencil CONTINENTAL Proteus leather brown 0.5

The "Proteus" by CONTINENTAL - a shape-shifter.
While this pencil can't predict the future, it can change its form just like its namesake, the sea god from Greek mythology. The grip sleeve can be easily and quickly exchanged for a completely different material (both visually and tactilely). This variability, highly unusual for the stationery market, is a natural consequence of our constructive guiding principle: We don't create black boxes. Instead of gluing, riveting, and pressing as is common today, we screw, plug, and connect in a way that allows all parts to be repeatedly detached, exchanged, and repaired. By changing the grip sleeve, our "Proteus" transforms its appearance in seconds. For those who find this "superficial" changeability insufficient: With a few simple steps, the pencil can also become a ballpoint pen and vice versa.

A word about the ballpoint pen's inner workings: The base frame is made of solid brass and houses a German premium fine lead system, the DSM 2007 from Schmidt Technology in St. Georgen in the Black Forest, driven by the world's only push mechanism made entirely of nickel-plated brass, the SKM88 DS from the same company, and filled with two Mars® micro carbon leads from Staedtler in Nuremberg in HB hardness. Other degrees of hardness and refill packs are also available from us.

In this case, the fine lead system is designed for leads with a diameter of 0.5 mm. The solid brass frame was wrapped in pure vegetable tanned leather from southern Germany. The leather is untreated, meaning it has neither been sanded nor oiled, and has been tanned using exclusively plant-based tanning agents without any synthetic substances making it durable and subtle.
