This  set of vinyl indicator / flag numbers are for when you redo your ugly, rusted flags in your old cash register. This does most any small machine  (1, 5, 6, 11, 12, 311, 313, 317, 50,  and many other models)These are for indicator flags that are 1 1/2" wide . These are the finest most perfect set you could make. I have been using these for years, perfectly spaced, same size numbers with no flaws.  These are guaranteed to not EVER get an air bubble under the vinyl which looks very amateur. AND these are NOT shiny black vinyl as others are. Have you ever seen shiny numbers on flags? NO>>> I also have sets for the wider 1 3/4" flags. also available for most any register  --  inquire with your needs buyer to pay 1.45 postage
