Pair Mid Century Modern Lamps Geometric Ceramic Fiberglass (some repair). I believe these are ceramic or plaster.  There are no chips or cracks.  There is surface wear,  some scratches and staining.  They do need a better cleaning but some of the stains are probably permanent.  The shades do have a lot of stains.  I did not try to clean them.  One shade has a dent.  There is also some loose string along the rims. They are 30.5" tall with shades and the base is 6.5" at the widest.  They need repair. One lights up when the push button is wiggled and the other does not light up (the one with black stains under socket area and torn fabric on bottom). They have different cords so I assume one was repaired at one time.  They will be shipped with the shades nestled into each other so save on box size and cost. These do need some new wiring and surface restoration so please look at pictures closely and ask any questions.  I am happy to send any additional pictures of areas you would like to see closer.
