Here are sculptural objects in the form of eggs. They are probably made of cast acrylic. They have white bottoms separated from transparent tops, with suspended yellow yolks. Each egg (there were 9 available in the listing!) measures approximately 3” in height and 2” across. While they might be used as a paperweight or desk object, there is no flat side for stability. No identifying maker marks.
