The 3rd one didn't upload right and my memory sucks. The important things with the molds are, use common sense with your spacing. 9 fits fine in a large flat rate box. Make sure the insulators are SNUG! when your done. That's one of the things said in the lost page, When your done, close your box and shake the #@*% out of it and see if there is anything loose or rattling. If there is, FIX it or trade spots or whatever you have to do. I had to stand on one of the boxes to get it closed and tapped up that I sent John. That was TOO tight. But it shows what weight they will handle! I tested this nifty invent out outlaw style. If you put plenty of tape around the stress areas of the box, I'll put my word on things to be close to idiot, (oops), I mean rough shipper proof! Sometimes you have to re-cut a little bit in a few places to get the lid closed. BE PATIENT. If your not a patient person, Email me and I'll make you some molds and send them to you.
