Turns out instructions would have been a good thing! I'm struggling a bit on the best way to actually load it to full 2x3 capacity and still be able to pull the butts and shafts out without extreme measures. The one thing I know for sure (at least in my situation) is that the thicker ends of the butts and shafts have to be inserted opposite each other. That is to say, either butts joint down/shafts tips up or vice versa. It ain't happening any other way for me. I also have learned to leave a little of both the butts and shafts sticking up so I'll have something to grab on to in order to pull them out. I've also been using one of those lid grippers out of the kitchen to help get a hold on the pieces. I do have a little arthritis in my hands and fingers but still, these cases capture the butts and shafts really tight. I realize JB wants to make the cases as small as possible for easy handling and transport and I sure appreciate that, but maybe 10% bigger wouldn't hurt? In any event, I'm more than willing to live with it given all the other good things about the cases.
Having said the above I have already ordered my second one, a 1x2. The quality on these cases seems terrific and I think the price is very fair.
