### ⭐⭐⭐⭐⭐ these tiny things make a big difference
*by S***E on August 14, 2024*

It always amazes me how little I know about how things work. I understood that old typewriters had ribbons that needed changing often. My laser printer needs new toner occasionally. I still use carbon paper at times, and it is changed when needed. However, my adding machine numbers could no longer be read. What to do?? In looking at new machines, they seemed so expensive. Surely, I thought, something in that machine can be reinked. Then YouTube came to the rescue. I watched how easily the small ink roller could be changed. No way I thought, but I ordered these Ink Rollers just to try. Within a few seconds after receiving them, my machine's numbers were again readable. The most difficult part of the process was opening the package, and that only took a few seconds as well. Little things often make a big difference; these most certainly did.
