These were garnered from a large old estate. They may be Czechoslovakian(?) Crystal but I can't be 100% sure. Definitely Art Deco style. Graduated crystals are in excellent condition. All wires and hooks and strong and fully functional. Would most likely fit a standard large candelabra bulb. Standard 60w bulb is too large and appliance size bulb is too small. The shades are 4" tall and the adjustable bottom is 3" when fully closed. Will fit larger bases. Shipped... with USPS Priority Mail. Please see all photos as they are an important part of the description. Please ask for any additional photos you think I have missed in posting. Questions are always welcome.
