Grenadilla (African blackwood)

Grenadilla is a deep brown to black hardwood, belonging to the ironwoods. An absolutely perfect material for a writing instrument. Its natural warmth flatters the hand, and due to its grain and structure it is extremely hard and unique. But before a precious wood is ready to be used, it needs to go through a process of ageing and drying for up to 7 years. We only use woods that are ecologically sustainable and have a certified origin.


Ebonite is a particularly hard and solid material made of natural rubber and sulphur, which can be shaped with great precision. In 1851, Charles Goodyear applied for the patent for ebonite. The name of the black material is a reference to African ebony. The natural rubber itself is obtained from the rubber tree (Hevea brasiliensis). To extract the raw material, the bark of the rubber tree is scratched so that the latex seeps out of the tree.


Cocoon and the pen cases are made using carefully selected, high-quality leathers. The premium cowhide is purely vegetable tanned in a southern German tannery and is characterized above all by its noble sheen and brilliant color. In addition, this leather has a distinctive feel and an exceptional scent. These premium hides are processed with great effort by one of the few remaining leather manufacturers in Germany. Craftsmanship is created here with almost two hundred years of experience – that's something you can see and feel.


The carbon fiber tubes are manufactured using the pull-winding process. In this process, reinforcing fibers are wound onto unidirectional layered pieces by rotating winding equipment. This double fiber winding results in a higher flexural strength and torsional rigidity than pultruded, extruded tubes. Grinding gives the carbon tubes an elegant, silk-matt surface.
