Small heart key charm earrings in antiqued brass or silver. Matching necklaces are also available. The earring hooks are nickel-free brass or sterling silver. They can be washed in water but are not recommended for wearing in the shower or while swimming. The necklace is on 18 in of chain, however, I can make it any length, just leave a note at the time of purchase if you need it longer. Don't forget a matching ring or set of earrings.
