This is a play cue with a beautiful cherry blossom inlay. Radial joint with joint cap. Shaft: 12mm ferrule diameter, conical taper. *At our workshop, we have processed the weight hole to accommodate MEZZ weight bolts. Weight bolts are compatible with MEZZ, but longer ones may not fit. Weight bolts are not included. Due to the nature of wood products, please refrain from purchasing if you are seeking perfection. *Similar items from other sellers do not allow for weight adjustment. I personally like the design of this cue and use one for play. The shaft taper is unique, and I feel that this taper reduces miscuing. Changing the standard tip to one with better ball release will make it easier to achieve spin. The above is a personal opinion.
