Architectural Hand Cut Crystal Pulls Set Mid Century Modern Bronze Hardware

Object d' Arts, entertaining five shiny multi sided crystal balls mounted on bronze or brass in set. The cuts and shines are spectacular, and decorative. Very likely from Italy and for the high quality costume made doors.  The few of those plates accommodates screws and nails to be installed on doors, drawers, or banisters. The condition is fabulous, aged in and on the metal parts. They are very heavy, and each weights about more than half pound give or take. Suite of 5.  dimensions: 2.75" x 2"
