The deep black casing is subject to an elaborate process. The material of the casing consists of high-grade resin and it takes month until it is finished, whereupon the tailor-made plating is curved and cut into a contour using a natural diamond.

The ballpoint pen K800 with twist mechanism comes with a large capacity black refill.
