HP 51640A (HP 40) Black Pigment-Based Ink Cartridge

Each month, we acquire thousands of surplus, unopened OEM name-brand printer cartridges from companies transitioning to new printers. These cartridges are typically unused but are often discarded. We purchase them at heavily reduced prices and pass those savings along to you.

The cartridges arrive in different states—some are still boxed or sealed, others may be out of their packaging, and they range from current stock to expired items. No matter the packaging or expiration date, you’ll always receive a brand-new, name-brand cartridge guaranteed to work just as reliably as one purchased at full retail price.
