on shipping pachinko balls

[mudfud]

hey guys.

I have an observation, after buying about 10k balls and having them shipped.

if the seller leaves any space in the box and the balls can shift, often the package will burst.

also, if they overpack a box, with tension, it will burst open. see picture below. I think the post office noticed before too many got away... they must think we're nuts when they have all these ball bearings go through the system. my carrier always thinks something broke inside the box

one seller I tried to suggest putting a wad of something to prevent the moving around, and he insisted that the USPS said to do it the way he had (luckily with ziplocks that kept them from getting away mostly)

stopexpress has been the best seller for me: double ziplocks and no space to shift in the boxes, no lost balls.
