If you have misplaced your metric ruler, remember that 13 mm=1/2 inch.
Remember: The wider the magnets, the more comfortable the earring is.
If you are allergic to nickel, order only earrings that have both enamel painted ceramic magnets front and back since the neodymium magnets are plated with nickel.
