Our Mission
Our mission is simple: to deliver the highest-quality replacement ink and toner cartridges at the lowest possible price, backed by knowledgeable U.S.-based customer support and a 100% satisfaction guarantee. We exist because no one should pay more for replacement ink than they paid for their printer.
Our Story (Founded 2005)
Castle Ink was founded in 2005 by Lauren Elward and William Elward after they grew frustrated paying more for replacement inkjet cartridges than they had originally paid for the printer itself. They believed consumers deserved a better, more transparent option, so they set out to source premium aftermarket cartridges, test them rigorously on real office printers, and pass the savings on to customers.
Two decades later, Castle Ink ships cartridges to customers in all 50 states from our Long Island fulfillment center. We have been featured in The New York Times, profiled on CrunchBase, and recognized by industry reviewers for our commitment to value and sustainability.
