The magic of Arco is in the material. An overlap of transparent and opaque layers bonded by a golden glue is first cut to size and then lathed with a 4-degree slant. The outcome is a semi-transparent and iridescent material, reminiscent of celluloid. Arco is fitted with a piston filler system, Pineider's patented magnetic locking system, and is numbered and limited to 888 pieces. Available in fountain pen, rollerball and ballpoint mode (TBA). The nib options are: EF, F, M, B, S.
