I made these plugs out of sterling silver and oxidized the low parts for a striking contrast.
I coated them with a special varnish to prevent tarnish.
Earring tubes measure about 10mm long. I can finish the backs one of three ways (last photo) either straight tubes, flared, or with a groove for the o-ring.
