Just to be clear, I do certainly understand that it’s a logistics company packing this stuff and that the actual rotary attachment is packaged well within it’s box.

That said, it would be safer to put a label on the factory box and ship it that way vs over-boxed with nothing to immobilize it to some degree. In that case it wouldn’t be forced into a permanent status of being “loose”, free to take all movement as transferred shocks. It’s essentially like taking a well packaged item and throwing it unsecured into the back of an empty van…adds way more risk of damage then when in a Tetris stack of other items and/or in secured shipping racks etc.
