Graf von Faber Castell Biros with guilloché barrel

The surface of the ballpoint pen is crafted in careful handwork with a guilloche pattern by the traditional company Graf von Faber-Castell. A grain guilloche is engraved on the barrel made of precious resin, which is further refined through additional manual processes, giving it a unique appearance. Each writing instrument is individually made and of high-quality rhodium, making it a one-of-a-kind piece. The ballpoint pen features a twist mechanism and is equipped with a large-capacity refill that writes in black with a B thickness.
