Earrings swing and twirl....so why not make the back side beautiful also? A fun red and white polka dot print is on the back side. 
Earrings are cut and sanded, for smoothness, from the 2 tins in the images. One a Vintage English Tin and the other a Contemporary Tin.
Earring wires are antique gold-plated brass, 16mm flat fishhook with open loop, 21 gauge.  Each pair come with silicone clear earring backs. 
Earrings have been treated with a museum grade wax to protect and enhance, called Renaissance.
Some of the tins are vintage and have been lovingly used over decades. Therefore, there may be fine scratches or imperfections.
