Twist-action ballpen manufactured from highly-polished brass and chromium plated on all external parts. The distinctive feature of this pen is its precision-machined diagonal guilloche pattern on the barrel prior to electroplating. This machining process is slow and exacting and requires considerable skill, but the visual result is stunning. The Biarritz Ballpen is complemented by a brass refill containing German Dokumental™ ink and Swiss tungsten carbide tip, capable of writing an astonishing four thousand metres. Engraved to the upper part beside the clip. Each pen is supplied in a PB200 Presentation Box.
