Our refillable cartridges were created to simplify the refilling of printers using HP 934 and 935 original cartridges. Refilling InkPot's refillable cartridges is as easy as counting one, two, three. 1- Remove the cap. 2- Inject ink. 3- Replace the cap. That's all!

The cartridges are provided with permanent chips. Although these chips will not display accurate ink levels, the cartridges are transparent, so you can always know when you will need to refill.

*IMPORTANT* The cartridges provided with this product are empty. You will also need to purchase an inkjet refill kit that is compatible with these cartridges.
