Cranberry mauve studs in a great moonglow lucite & a deep rich color. This is the 'Retro Button Stud' style & is a domed button with a flat back. This pair measures just over 1/2" or 15mm in diameter. See the pic of the model in the Retro Button Studs in another color, but the same size to get an idea of scale when they are worn.
Most all earrings are made with vintage lucite parts that were made in Rhode Island in the 1960's - early 80's by Best Plastics. We hand-set them with surgical steel earring posts and they have sturdy surgical steel/acrylic backings on them as well. Light-weight & fun to wear.
