Comments about Refill Kit for HP 21 & 21XL Black Ink:

This refill kit is super easy to use. Its refiller now has a screw to turn to push the ink through the needle instead of having to push down with a finger. This refill kit fills about 10-15 cartridges with hardly any mess. I've used this product for about two years with satisfaction. It's cheaper than buying individual cartridges of black ink.


It pays to refill your own black ink.

Comments about Refill Kit for HP 21 & 21XL Black Ink:

I got what I ordered, same as I reordered before. The black ink is black. It came in good time despite the weather. I haven't had to use it yet so I cannot say if the new ones are equal or not.

Comments about Refill Kit for HP 21 & 21XL Black Ink:

I've bought this ink refill kit before and it is exactly as advertised. I try to be extra careful when I use it because, let's face it, ink is messy! With a little caution, you can save quite a bit on ink!!! YAY!
