does what it should, quick service got my delivery within three days.


Second order placed with Stinkyink after a satisfying first order. Order placement simple on easy to understand website and with clear instructions, giving choice of inks for my printer. For the first time I have deviated from branded ink...yes to save money....and do you know what...it works and is just as good!
I was also impressed with the post order communication and delivery efficiency, plus packaging. All in all a good experience and...to quote Arnie...I'LL BE BACK"

PS I'll probably copy and post this response on other orders placed with this order....I won't apologise for repeating myself...
