The Cue Cube combo features the classic cue cube and the popular shaft slicker. The Cue Cube features a scuffer on one side and a nickel shaper on the other. The Shaft Slicker has a gentle, not abrasive cleaning side that removes the dirt and oils that accumulate on the cue from repeated use. The specially treated soft natural leather smoothes the shaft for a perfect stroke. The Shaft Slicker is only to be used on wood shafts – do not use on Fiberglass or butt end of cues.
