Review on FJA Products Universal Typewriter Ribbon - Twin-Spool Black 1/2 Inch Ribbon on 2-Inch Spool by Mark Fleming

Excellent ribbons! They are well soiled, tested on 2 typewriters, a 1937 Smith Corona and a 1940 Royal portable. Worked very well! I read some reviews about the lack of installation instructions, I don't see the point. These tapes are exactly the same as the ones I used 40 years ago. If you need to know anything about installation, please refer to your specific typewriter's manual, as while different brands are similar in terms of installation, there are slight differences in how the ribbons work. I am very satisfied with this product!
