These cartridges are the original HP ones, not some imitation (imitations my machine doesn't seem to like or tolerate because of stuff built into it by HP). They come in the same box as the ones you would buy at the XXXXXX and XXXXX stores, just a better price. If you can get these shipped free (like you belong to Overstock's free shipping deal), they are a very good deal. If you have to pay shipping, you may get a better deal on some sales at "regular" stores. As to quality, since they are HP originals, the quality is there (but they still don't last very long, considering their price). The extended long life cartridges last quite a bit longer, but they cost quite a bit more. These cartridges are easy to take out of machine and install the new ones, so I just buy the regular size.
