Retractable ball pen with a natural bamboo barrel and shiny chrome accents. The Ancona Bamboo Inkless pen features a special metal alloy tip that as you write, deposits tiny amounts of this metal onto the page resembling the look of a pencil on paper without the tip wearing down noticeably. It has an inkless refill which is a great environmentally conscious alternative. Bamboo is a natural material that produces unavoidable variances in the grain pattern, colour, and branding.
