This cute round stubby knob came off of a desk drawer. The knob measures 5/8 inch across the top and projects 3/4 inch from the surface of the drawer. At the base, the knob is treaded to accept a screw or dowel screw. This one has its original dowel screw–to insert to the front of the drawer. It could be removed, however, if you wanted to insert a screw from the back of the drawer front.
This one is a hard one to find!
