This item is being sold by 8ball9ball here on AZB to carry cue extensions . Since I am short and never get shape...I rely heavily on my cue extension so this solution for carrying an extension made sense to me. I ordered the Piggyback case from 8ball9ball and received the custom sized case several days later. The fit is perfect for my case and now I have more room for gadgets and googan-esque items in my case! It's a very practical accessory, the price is right and the service is top notch. Thank you Mr.8ball9ball. :thumbup:
