I have to call it a 3 x 6 because it only has sleeves to hold 3 butts and 6 shafts, however, the sleeves are sort of oversize and if you don't mind putting shafts and butts or multipal shafts together it will accommodate the following without any problem.
Just remember, your getting the options of carrying the following cues and shafts for the price of a regular 3 x 6.
3 x 6
3 x 10
4 x 8
5 x 6
If anyone has any questions about this, please email me at jjustis4@aol.com instead of using the PM. Sometimes, I forget to check the PM and it could be days before you get an answer.
