Red Cup Shot Glasses. Double Size. Remember those plastic red cups you played beer pong with? Well here they are in a Miniature Size. A Resin or at least Hard Plastic. Bright Red on the Outside, White on the Inside. Each glass is about 2 1/2 inches tall and about 2 inches in diameter at Rim. I find no markings on the bottom of these. No Chips or Cracks with all Color Strong and True.
