We suggest the COVER-UP-SHEETS as a replacement. The COVER-UP-SHEETS by Ko-Rec-Type contain 32 1"x2 3/4" tabs and will correct up to 5000 typing errors on originals.
These old time Cover-Up Typewriter Correction Paper Tabs work with all typewriter ribbons. They are great to use with the old universal twin spool Nylon Ribbon. They are comparable with today∆s white out products, but made to quickly correct typewriter errors. Cover-Up Tabs are easy to use and do not leave a mess to clean inside your typewriter.
