Very nice vintage mottled Brown pendant or cased teardrop floor lamp or hanging lamp shades. I have seen these on floor lamps and I have seen them used with heavy hanging cords from the ceiling. Either way you would probably have to get some adapters to make them work they are seven and three quarter inches tall the bottom opening is 4 in the top is anywhere from an inch and a half to an inch and 5/8 or there about. Now all three of them has some chips in the top area which accounts for the size variation. They're not bad but these are probably not new so they have been used some. Any adapter that you get to make these shades work should cover up any of that especially if you're using them for hanging because they have something of a rubber and plastic adapter that goes in there that you can get it lighting stores so these are really nice and being cased on the inside makes them even better very nice set all the way aroud even with the slight damage
