My Earring Buddy ®
   uses powerful 6mm (a little over 1/4") Neodymium magnets
       that strongly hold to each other with the earring backings in between.

Clip earrings convert in a snap!

              Screwback earrings require the screw mechanism be
                  removed  (instructions included) and then convert to
    pierced in a blink of an eye.

It simply does not get any easier than this!
