I am not an advocate for shipping in ball cubes for precisely this reason. Find another way. Cover it in a ton of bubble wrap and it will be safer.

Ball cubes are rinky-dink garbage. The older ones were made with stronger material. The modern versions are so flimsy. Just a terrible product.

If you insist upon using a plastic case to ship, then use the ones that are round, conforming to the shape of the ball. Less chance of problems. But again, go crazy with the bubble wrap.
