I purchased eight of these Arched Square Cabinet 3 inch center to center arch pulls in the multipack of eight, for a custom made oak dresser that was made twenty years ago.  I used these pulls on the bottom four drawers, to go with the new knobs on the top two smaller drawers.  My old pulls were 3 inch center to center, which made easy installment for the new pulls  in the existing drilled holes. I am very pleased with the look, function, and quality of these arched pulls.  I highly recommend purchasing them.
