The bridge image is etched and the disc was cut out of cherry wood. The wood grain varies with every pair which makes each one unique and special. I hand sand the front and back of the disc so it is soft to the touch, add paint and then I finish it with a polyurethane finish. The lightweight disc is 3/4" high and 1/2" wide and 3/32" thick. The 18" long chain is gunmetal.
