Stinkyink continues to provide a quick, reliable service, and great products at competitive prices. Why would you go anywhere else? Keep doing what you're doing John, and I'll keep buying from you. It's that simple.


I have used the High Capacity HP21XL Black Ink for the first time, as it seemed great value. It was so easy to install, and the print-quality is first-rate, even on economy setting.

This is excellent service and top-notch products - why shop anywhere else? I recommended Stinkyink to my brother, who now always orders from them.

Another 'plus' is the recycling facility offered, so an all-round winner.


A great bargain the X / L size compared to the standard one.

The delivery time is excellent , almost next day.

With this product you get a lot for your money. Good value.


I use an HP Deskjet printer and these high capacity cartridges work really well. The print quality is good and they definitely last way longer than the standard variety. I always recommend them to my friends.
