Men's Magnetic 3, 4, and 4.5 MM Round Setting Swarovsky Crystal Earrings & Extra Magnets
Made especially for men with two neodymium magnets, with one attached to the earring and a 7 mm in back along with a free extra pair of ceramic backs in case the neodymium magnets are too strong for your ears. I say this after having 30 years of experience at art shows. However, I recommend my regular earrings(with a neodymium and ceramic magnet combination for an earlobe that is 1/4 inch or less in thickness.)
Sold in pairs.
Need extra or stronger magnet backs? They are listed here:
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.
Not recommended for children under 5 years old.
