A golf club head includes a body having at least one recessed portion for securely receiving at least one weight member. The weight member includes a lid with a plurality of protrusions respectively received in receiving portions of the recessed portion. At least one of the protrusions has a weight different from those of other protrusions. The lid has a symmetric shape the same as that of the recessed portion of the body, allowing the lid to be mounted in the recessed portion in one of at least two orientations that correspond to at least two different locations of a center of gravity of the golf club head, thereby allowing rapid change in the center of the gravity of the golf club head.
