WOPEX – writing the future! Not only does it offer a better writing performance, it also protects trees and forests. Thanks to our special extrusion technology, we are able to utilise more than 80% of a tree in the manufacture of WOPEX compared to 20% in the case of conventional pencil production methods. This is but one of the many STAEDTLER examples to illustrate that innovation and tradition can go hand in hand. It also clearly shows that it was not just our ancestors who were ahead of their time – the company STAEDTLER continues to be so today as well. How does the extrusion of WOPEX work? Granulates of all of the materials the pencil is made up of – wood, lead and pencil surface – are melted at temperatures between 130 and 180°C. A specially engineered nozzle, the extrusion head, ensures that the streams of the respective melted granulates are perfectly aligned in the right volume and correct position in order to ensure production of a uniformly homogeneous pencil. The density of the material means that a WOPEX pencil is slightly heavier than conventional pencils. This makes the innovative pencil extremely comfortable to hold, thereby offering a unique writing experience!
- Standard-size hexagonal pencil is easy (and surprisingly satisfying!) to sharpen with any good quality pencil sharpener.
- High lead stability and strong bonding ensures high break-resistance and a longer write-out length compared to traditional pencils.
- Set of 6 colours includes one each of: black, blue, red, green, yellow and pink.
