16 mm Black, White and Grey Glass Magnetic Non Pierced Clip Earrings

These are just really cool...they are black, white and grey glass with a bare hint of blue and each one has a little different pattern but I will match them as best as possible.
They are 16 x 6 mm high.
Two 13 x 2.5 mm (1/2 inch) enamel painted ceramic magnets hold them on your ear comfortably with no pinching.

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.
