2x3's arent very common case size (for some strange reason), 

which always surprises us since the 2x3 size

 makes so much sense. If you have a shooting cue, a breaking cue and a jump cue, a

 2x3 is exactly what you need. Just drop the jump butt 

into the handy jump butt pocket

 and you're good to go.

QK-S cases are built like tanks, for ultimate protection of your prized cues..
