SHARP's ribbon-free word processor paper, thermal paper, standard. Available in A4 and B5 sizes, I use both. About half of the B5 paper and about 70% of the A4 paper remain. These are quite old, so the paper has some stains. The stain in image 5 is on the cardboard backing. Please take a close look at the images and only purchase if you are satisfied. I am also selling word processor paper that requires ribbon cassettes.
