These are made on guitar picks with a pair of T-Rexes. Between the guitar pick and the earwire I used a 6mm olivine genuine Swarovski crystal bicone on each earring. They are 2.75 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, tarnish resistant). To get an idea of how long the earrings will be on you, start from where your ear is pierced and measure down. All of my jewelry and accessories are handmade by me. Made in and shipped from Lubbock, TX. USA
