Guilloches were decorative designs of fine engraved lines that adorned clocks and other accessories. This turns each guilloche writing instrument into a real gem. Each pencil, with a body made of precious resin, is engraved line by line with an elegant design that gives it a noble touch, thanks to subsequent lacquering and polishing processes. The metal parts are rhodium plated. The clip is solid, with spring. It features a hand-tested, rhodium-plated, handcrafted 18k gold nib with iridium nib. Cartridge-converter system, with converter included. M stroke (medium). Gulf Blue colour.
