This is one (so not a set!) double sided patriotic NSDAP cuff link.
No RZM markings, so that means it was made before 1934, the uality is decent but not as good as later RZM controlled items were. This is typical early patriotic item. Not easy to find and a nice add on to e.g. a party badge collection.
It is in good condition. Unfortunately only one, so NOT for two sleeves.
