LxTek Calculator Roller Ribbons Replacement for IR40T IR-40T CP13 MP-12D to use with Sharp EL-1750V, EL-1801V HR-100TM,HR-170RC,Canon P23-dhv CP13 (Black and Red, 10-Pack, Individually Sealed)

Less than the office sore brands. Great value! I have high volume usage so they last average one a month for me.

These worked perfectly for my needs, easy install have a brand new adding machine now. Color and readability was perfect. 👌

fits well with calculator. good ink. durable and Long Lasting.

Wish it was all black rather than the red/black rollers. Rollers have good ink quality which last with high volume calculator use. Will reorder every other month.

It works perfectly with my devices and saved money buying it here. I found other places that should this for double the price and less product. This was a score!

Works and fits right. Local office store no longer carries these, but I don’t want to replace my calculator yet!

FINALLY! An ink refill cartridge that really works! I love this product. I was having so much trouble finding quality refill cartridges, I thought I was going to have to buy a new calculator! I thought I’d give these a try and I am thrilled. I can see the printed numbers clearly and there is no excess ink mess anywhere! I could not be happier!

These are so much less expensive than the Office store brands. Great value! They come supersaturated with ink, which has its plusses and minuses. I am assuming they will print many more times than the standard type cartridges, but when they're new. they have so much ink that the numbers bleed into each other. This goes away as the ink gets used up. I have been using one for a month and it is just now getting to the normal no bleed state.
