Is Castle Ink a real company?

Yes. Castle Ink has sold printer cartridges online under the same name and domain since 2005. It was started by Lauren Elward, then a high school English teacher who was spending heavily on ink to print handouts for her students, and her husband, William (Bill) Elward. The couple funded the business themselves, and it remains independent and family-owned today. In 2012, CNNMoney reported on the Elwards starting Castle Ink from their Greenlawn home in 2005 and growing it past $1 million in revenue. That same year the entrepreneurship site Sramana Mitra profiled it in its 1Mby1M program as a bootstrapped, husband-and-wife company in Greenlawn, New York.

Castle Ink is an online-only retailer. It operates from Greenlawn on Long Island and does not run a walk-in store, so all orders are placed on castleink.com and shipped from New York.

Who owns and runs Castle Ink?

Lauren Elward is Co-Founder and CEO and has led the company since 2005. She oversees product testing and supplier vetting.

William Elward is Co-Founder and President, with more than 20 years in the printer supplies industry. He writes or reviews every guide on the Castle Ink printer-help blog and answers printer and ink questions publicly under his own name.

What does Castle Ink's guarantee cover?

Every product carries a 1-year, 100% satisfaction guarantee, counted from the day you receive it.

If you ordered the wrong item or changed your mind, you can return unused cartridges in their original packaging within one year for a full refund of the product price or an exchange. There is never a restocking fee. Return shipping is free for defective, damaged or wrong items; for other returns the customer pays return shipping. The full terms are in Castle Ink's refund policy.

A few recent reviews, quoted as written:

Are Castle Ink's cartridges genuine HP, Canon or Epson?

No, and Castle Ink says so plainly. Castle Ink sells aftermarket cartridges, not original manufacturer (OEM) cartridges. Its inkjet cartridges are remanufactured: genuine manufacturer shells that have been cleaned, refilled and print-tested in the United States. Its toner cartridges, drum units and ink bottles are compatible, meaning newly manufactured to fit your printer. Castle Ink is not affiliated with or endorsed by any printer manufacturer, and brand names are used only to identify which printers each cartridge fits.

What should you know before ordering?

• Some printers resist third-party cartridges. Certain HP, Brother and other models receive firmware updates that can block or warn about non-OEM chips, and HP+ printers are locked to Original HP ink. Castle Ink notes these models on the affected product pages, and the 1-year guarantee applies if a cartridge will not work.
• Ink-level readings may differ. Some remanufactured cartridges show a low or unknown ink level even when full. Printing continues normally.
• Castle Ink is a small company. Support is handled by email and the contact form Monday to Friday, 9 AM to 5 PM ET, by the same team that ships your order.
