Hard pool cue cases feature high impact tubes that hold your butt and shaft in place while you're on the move. These cue cases for sale can help protect against dents as well as warping. The smallest cases are referred to as one butt/one shaft cases, meaning they allow you to carry one cue butt and one cue shaft in the case. Cases typically go as high as three butt/seven shaft or even four butt/eight shaft. If you're a player on the go, a hard case is the case for you.
