Set of two. Includes screw-back and clip-on earrings. Both have silicone cushioning, so they should be quite comfortable and cause minimal earlobe pain. Worn about twice, but purchased about 3-4 years ago, so the silicone parts may have slightly discolored. The earring backing cards are bent, so I may ship them with different cards. Johnny's, mass-produced, "minefield" style.
