Böker Plus Redox Brass kynä 09BO037

In this particularly classy version, the innovative Boker Plus Redox Pen is supplied with a brass handle body on which a unique patina forms over time. It is based on a millennia-old technique that was already known in ancient Rome and was even used by Leonardo da Vinci and Albrecht Dürer for their famous drawings. The modern pen does not need a refill and works completely without graphite abrasion or ink. Instead, the Redox Pen takes advantage of the rapid oxidation that occurs when the Ethergraph tip comes into contact with the paper. This means that the pen does not wear out, does not leave any unwanted marks on hands or clothing and can be used without any problems even under the most adverse conditions. Moreover, once written down, it cannot be wiped away. The high-quality tip is made by the Italian writing utensil manufacturer Napkin. The Redox Pen looks like a classic pencil and fits comfortably in the hand. Supplied with a practical clip.
