These are brand new, My printer had an error code saying I needed new ink cartridges. Cost me about $200.00 with tax. I installed them, it didn't fix the problem. I took the printer apart and discovered the cheap off shore cartridges I was using leaked and totally gummed up the printer. I had to replace my printer. These are the high yield cartridges and are rated for up to 700 pages and are OEM original HP. This ink is used on the following models of HP printer: OfficeJet 6000 OfficeJet 6500 OfficeJet 6500a OfficeJet 6500a Plus OfficeJet 7000 OfficeJet 7500a. Go to hp.com to confirm the pricing.
