These are made on New Kids on the Block guitar picks. I used stainless steel chain and findings to dangle two 6mm genuine Swarovski crystal bicones - one white alabaster and one jet black - as well as a stainless steel "I'm with the band" charm from each earring.
They are 4.25 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.
