IR-40T, IR40T Black and Red Ink Roller x [3 Pack] Ribbon Cartridge Replacement Compatible with Canon P23-DH V, Casio HR-100TM, HR-150TM, Sharp EL-1750V, EL-1801V, Citizen CP-13 Calculator (3 Pack).

I almost returned this because it looked like it was all black. I accidently touched the "red" side, and the red ink came off on my finger. I installed this and it does in fact print in black AND red. The fact that the felt on the red side was also black was very misleading. This is a two color ink pad that works perfectly in my adding machine. You can't beat this for the price.

Not sure what took me so long to look for a replacement!

Exactly what I needed, easy to install.

"Package of Three" Canon P23-DH V Calculator... - I use this calculator constantly. This 3 pack ink replacement is at a reasonable price.

I was ready to toss out my very old adding machine because I could no longer read the numbers on the printed tape. I couldn't see any way to change the ink rollers.......but as a last resort I found a YouTube video which showed how EASY it was to change the ink roller. I easily found the replacement part on Amazon and it was here in a couple of days. I changed the roller and now I can easily read the printed tape. and, as another bonus it made me eager to take on some accounting projects I had been putting off.

worked and fit correct

Works perfectly-packed well-shipped promptly

Good product

I have received only 1 pack of ink roller instead of 3 ink roller and I initiated a return request and the person didnot receive the parcel
