Twist-action ballpoint pen 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 Ballpoint Pen is complemented by a brass refill containing high quality ink and Swiss tungsten carbide tip, capable of writing an astonishing four thousand metres. For personalisation or branding we recommend engraving or printing on the upper part beside the clip.
