This is the second pair of studs I've gotten from this company and I really should have known better.  They should include at least one extra earring back with every order.  The backs themselves really are impossibly small and impossible to hold onto.  Even the average sized fingers are too large to handle these backs.  Within 5 minutes of opening the package and trying to put the earrings in, one of the backs is lost forever down my bathroom sink drain.  Oh well......
