Made by Liz, sister of Daniel Roseberry, the artistic director of Schiaparelli. Such a talented family! Liz makes these earring backs and sells them in her etsy shop. I bought these, tried them on once, and never wore them out. Perfect condition, and include complimentary stud earrings (as shown). You can use them with any studs you already own, too.
