These jars are made of glass, and each has the metal clamps which hold the top down. The floral design is repeated around the entire outside of each jar. They are approximately 6-1/2", 8-1/2" and 9-1/2" tall. The smallest jar has a chip on the outside edge of the cover, near the clamp. The gaskets will need to be replaced in all three. Otherwise these are in very nice condition.
