First look at the surface color and protective film of the handle, whether it is damage and scratches or not.
The quality of the handle must be researched from the surface. See if the surface treatment is smooth and the pull is comfortable. Good handle should have a smooth edge, no thorny, and feel comfortable.
It is the best to choose a handle with a larger area around of the screw hole. Because the smaller the area around the screw hole , the more precise position of the handle hole on the board, otherwise, the slight deviation will cause the handle hole to be exposed.
