Ferris Wheel Press fountain pen inks feature a premium water-based formula designed for low-feathering and optimized for every fountain pen nib. Known for being highly saturated and low-bleed, the Ferris Wheel Press ink formulation is compatible with all fountain pen feeds. The 10ml ink pot is a sturdy plastic bottle with an opening almost as wide as the little bottle itself to allow you to fill your pen directly from the ink bottle with many fountain pens. Each Ferris Wheel Press Superman Collection 10ml ink pot fountain pen ink features an Art Deco style label showcasing Superman iconography (with lore snippets engraved in the cap’s collar). Collectors will adore the fantastic presentation with embossed label artwork and a detachable lore card chronicling Supermans journey.
