Swartz Ink Compatible Ink Replacement for P23-DH V Calculator Black and Red, 6-Pack

Good product

These ink rollers are certainly worth the money. Not sure if it's my calculator, or the roller, but a few of the digits are not as dark as I would like. However, it's still a great improvement over what I had.

Fits the calculator properly. Would buy again.

These are not "Canon", but they work pretty good and the price was great. I couldn't find these at any local office supply store at any where near this price. You just pop out the old ones and pop these in. Again, they work great and I would highly recommend these.

They are ok I guess, but do not last very well.

I got the multi pack because the ink cartridge intend no to last long.. They arrived perfectly package perfectly, it's nice to know ice got extras

I haven't used any of these yet but they look like exact duplicates of the cart that came with the calculator.

Arrived in good shape with no shipping issues. Still using the first one with no issues. Fit in calculator as easy as original. Hopefully the balance of the units will not dry out before use. Very well satisfied.
