Earrings are cut and sanded, for smoothness. These were created from 2 different contemporary tea tins.
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.
Ear wires can be switched out to a hypoallergenic Niobium, or sterling silver, if desired. The niobium is a gun-metal grey color. The added cost is $4.
