Vintage Porcelain Button Cabinet Furniture Knobs Pulls - White 3/4 in. Projects 5/8 inch from the surface of the drawer or door. A couple have some porcelain chipped off at the base.

All in new condition

I acquired these back around 1980 when I was rehabbing my house.  These are the ones I did not use.
