The magic of the Pineider Arco Stilo Rainbow Ballpoint Pen is in the materials that give it that luminescent glow. An overlap of transparent and opaque layers bonded by a golden glue is first cut to size and then lathed on a 4-degree slant. The outcome is a semi-transparent and iridescent material reminiscent of celluloid, aptly named ultra-resin. This limited edition Pineider ballpoint is numbered and limited to just 888 pieces. Made in Italy.
