Review on 🖨️ Porelon 11216 Universal Twin Spool Calculator Ribbon, 6-Pack: Black/Red - High-Quality Ink for Efficient Calculations by Kyle Smithlin

The ribbons I received were almost empty. I don't know if they dried up or never had ink. Maybe it's an accident, but it's a complaint from others, so at least a percentage of those feeds are useless. I placed an order on January 18th and received it a few days later. It's March 6th and it's already as pale as the one I replaced which was in the calculator in February 2018 when I got it. So the original tape lasted from mid-January 2018 to January 2020. - about two years. This thread lasted a month. I have five left. Lets see what happens.
