These beautiful top quality 14K Gold Filled lever back earring findings are interchangeable because the loop is open on the inside of the earring. You can slide any dangle on or off while the earring is open, but it cannot fall off when the earring is closed. Perfect for customers who want to convert more than one pair of earrings, but don't want to buy lots of lever back earring backs. Create earring 'sets', with multiple dangles in a wide color range - so you can match any outfit. Quantity: 2 lever backs (1 pair), measuring 10mm x 16mm. 21 gauge wire.
