💡 Porelon 11204 PR42 Calculator Ink Rolls, 2-Pack,Black/red: Efficient Ink Replacement Rolls for PR42 Calculators Review

I have a Canon P170-DH which they are compatible with. I bought a twin pack and the first reel I put in didn't let the number wheels work freely. After using it once, the carriage could not return home correctly, so red/black would not be correct and the characters on the right would be confused. The second reel works perfectly. I wouldn't buy them again.

Stay with Porelon. A well known brand you don't have to worry about the ink rollers coming to you completely dry like the usual junk that is sold. I've been using Porelon products for years with no problems!

DO NOT buy these - they are old and dry. Don't waste time going back to UPS. Waste of time and money, not to mention the inconvenience.

Fits right, easy installation, reasonable price and quick delivery. If you don't use both at the same time, seal the second one to keep it from drying out.

Ordered these for my Casio model HR-100TM electronic calculator. They fit perfectly and were easy to assemble. There was also a good supply of ink. Will definitely order again. To update. I checked my order date and had them for almost 2 years before I needed a second one. I taped the package to keep it fresh but it dried up. I would like to be able to buy them individually but they are hard to find.

I ordered a Porelon PR42 paint roller and received an unnamed IR40T paint roller with Chinese characters on the box. IR40T. I was afraid to open it in case it didn't work and I might have to send it back. I went ahead and opened it up and it will work, but it doesn't fit as well as Porelon. I am very disappointed to order the brand name. product and get an unnamed brand. Very deceptive.

The last 3 orders from this supplier were wrong and the ink is clogging the numbers and you can't see them on the ribbon! We want our money back!

I was about to buy one from my local shop when I saw this one at Revain for a much lower price and it works the same as the more expensive product. . I'm glad I bought it.
