Really works.
I didn't realize how bad I needed to replace until I got new ones. I live in a small town without access to certain supplies. It is good to have Amazon just a few key strokes away.

Easy to replace ink, tank you Amazon
So pleased with my Sharp refill imk.It was easy to put in. It came with red and black. I never realized that Iit had red, but now it shows up when you subtract it shows up in red. Thank you so much for having your product on Amazon.
