Stamped Brass Decorative Keyhole Insert

I purchased these to replace the keyhold inserts in an old secretary desk after it was refinished. I am keeping the old ones and throwing these new ones away! while the face looks flat, the back side that rests against the surface is not flat and it rocks back & forth. And, the sleeve that lines the inside of the keyhole is not long enough and is tapered inward. This product is flimsy and needs a longer sleeve . I will be looking elsewhere for these.
