Excellent replacement cartridges for Sharp calculator

So far, so good. Just like the branded calculator ribbons!

works great

I used to get another brand that I really liked; however, Amazon seems to no longer carry that brand. I went through a couple of others that didn't have the same quality and I came across this one. In the past month I have used two and the ink quality is fantastic. It takes me about four rolls of paper before I have to change a cartridge and that's good because I am on my calculator for 10 hours a day 5 days a week. Hopefully Amazon keeps these in stock because this will now be my go-to brand.

We were looking for a replacement ribbon for our office adding machine, as ours was running out. We were replacing a original Monroe ribbon. These replacement work perfectly. We've gone through three or four of them so far and all have worked seamlessly!

Great for the money but made cheap. Ribbons seems to have lack of ink in it, the reels are easily broken off. I drop one and the reels have broken off, but still able to use it

As described. No issues.

Compatible with my calculator. easy to see printing.
