Roller Vintage Japanese Dry Razor

Roller Vintage Japanese Dry Razor with case and extra blades. Not sure of date of manufacture, probably 1960's. The razor is mechanically powered and does not use electricity or batteries. Condition appears to be very good as it was probably not used since it still has a full tube of razor blades. The minuscule  blades are quite unique. About and inch and a half long, they are not flat but angled 90 degrees with one edge sharp and one not. The come in a tiny tube with groups of blades wrapped in waxed or oiled paper. The instructions are in Japanese if you take a picture and send to google lens it translates quite well. You could try to figure out how to use it or think of it as a really cool collectable.
