Exactly what I needed. Will buy again. ### ⭐⭐⭐⭐⭐ Review *by K***O on 5 November 2023* Does a great job in replacing the ink on the machine. However them machine itself is not the greatest (we got rid of it). The ink in the original went out fast. I would recommend a different machine but if you have the machine this is the ink for you. ## Frequently Bought Together - (6 Pack) COMPUMATIC Compatible/Replacement Calculator Ink Roller, Black/Red IR-40T, for Casio HR-300RC HR-200RC HR-170RC HR-150RC HR-100RC HR-100TM HR-150TM and More - Casio HR-170RC Plus – Mini Desktop Printing Calculator | Check & Correct, Cost/Sell/Margin, Dual-Color Print | Ideal for Taxes, Bookkeeping & Accounting Tasks - Universal UNV35720 16 lbs. 1/2 in.
