I have two of these vintage clear satin glass hobnail light or lamp shades with ruffled and crimped rims. They're 4-1/2 inches high by 9 inches diameter across the rims. The fitter openings are 1-3/4" diameter encircled by one-inch rims. Total width across the base is 3-1/4 inches. The shades are in excellent condition with no chips or damage. Price is per shade.
