I am using my HP Deskjet printer so much these days and am glad to have a reliable and economical source of ink. many thanks


This HP21 was as a result of a failure of one of the double Stinkyink cartridges I had purchased. I contacted Stinktlyink by phone to discuss and was met with the best lady representative at the other end which was a super surprise. She dealt with my problem in a very charming and professional mannor and I received the new cartridge the following day. Bravo to your Customer Service department - it was110% for me. Many thanks indeed.


This replacement cartridge seems fine. Thank you.


great thanks works as expected and a lot cheaper than buying direct from brand!

I have a HP Deskjet 2050A. Are these cartridges compatible


The HP 21 cartridges are not the correct inks for your printer, your printer takes the HP 301 and HP 301XL inks. If you need anything else or have any questions, please don't hesitate to contact us.

Yes, that cartridge can be used in the F300. The printer and all cartridges for the machine can be found here: http://www.stinkyinkshop.co.uk/hp/ink-cartridges/hp-deskjet-f300
