These 2 Vintage Tins marry so well together. Earrings are cut and sanded, for smoothness, from the 2 tins in the images.
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 Tins are Vintage and worn and add a Unique element to the Design.
