Hard acrylic black plastic cabochons that look and feel like glass, but are much lighter in weight. These are 13 mm wide and 7 mm high. Held on with 2 13 x 2.5 mm ceramic magnets, one attached to the earrings and one that goes behind your ear to hold it on your ear in complete comfort.

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.
