I am not trying to discourage you by any means,, but more observations on the straps. If you can, avoid them. As I said in my previous post, there are so many things for anything on a piece of luggage to be snagged on, minimising that risk is paramount. My coroplast box came with two straps that were "riveted" to the box. They got caught, and ripped out of the plastic. If the box is held enclosed only by the straps, you could be in a spot of bother should one or both get snagged and ripped off.
