"Package of Two" Monroe 5130, 5140, 5150, 7130 and 7140 Calculator Ribbon, Black and Red, Compatible, Convenience Cartridge

Very hard to find replacement ribbon for adding machine. Staples doesn't even carry it. So happy Amazon does. Love the old time adding machines

I got these for my mom she has an old calculator and she thought she was going to have to by a new on and I found these for her and now she can keep her calculator and they work great

They work fine in the calculator but came in one plastic bag together which was messy.

Works fine. Packaged loose, so a little messy.

Just what I ordered

When I tried to copy a colored picture, it smeared every time. Had to take it to UPS for copies. These ink cartridges were for Monroe 7140.

Been looking for this product for a long time and was glad to find it on Amazon. It is the only kind of ribbon I can use.

I ordered some tapes from another vendor and they did not work. These were great.
