These very whimsical, novelty cufflinks have a completely functional wheel on each cufflink.  

Each cufflink is a roulette wheel that has a ball that you can spin from the spindle on top.  

They are marked AUSTRIA and they are in very good condition.  

The roulette wheel is about 11/16” (17.5 mm) in diameter.  

These mid-century cufflinks make a great gift for the man with a gambling spirit.
