These shades appear to have had the tops cut off.
There is a
buildup of excess glass inside the top rim of each shade.
Along the top rim of each shade are very tiny cracks,two on
one and three on the other. You have to look very carefully
see them. They measure 3 3/4" along the bottom, and 2 7/8"
from the top to the bottom. The top measures 1 1/2"
