Remember when 'exercise' was called 'calisthenics'? I think I am dating myself. My brain had to do calisthenics in order to figure out how to put these earrings together when in actuality, it was incredibly simple. The cool thing is that you can carefully slip off the gold ball dangle and wear the earings as a hoop. Keep the rubber ear post stopper on (when you have the earring on or off) to preven the yellow gold ball from becoming lost. Gold filled components.
