LD Black Ink Refill Kit For Hewlett Packard (HP) 21 21XL
easiest to use refill kit yet
I found the instructions awkward at first until I realized that the syringe was for extracting the "overfill" and then all was well. It is a well designed kit and my cartridges work well. I'll know more once I see how many refills I get out of the package but it looks very promising.
