The ear-wire on these delicate little earrings is plated in sterling silver. Dangling from that is a sweet, antique-style silver key. Perfect little gift for any woman. (Or for you to keep to yourself.) Keys are approx. 0.75 inches in length. Hand made and ready to ship from a smoke free home. Please read my shop policies. By making a purchase, I assume you have read and understand the policies of Mommy Finds Time.
