These earrings are made with Nine Inch Nails Trent Reznor guitar picks. I dangled a 10mm black pave bead from each earring.
They are 3 inches long from the top of of the ear wire curve to the very bottom of the whole earring, and they have stainless steel earwires (nickel free, hypoallergenic, no tarnish). To get an idea of how long the earrings will be on you, start from where your ear is pierced and measure down.
