I still haven't opened the ESD bag. To be fair it looks like the tubes could have barely fit, diagonally. But I have never seen Mouser bag IC tubes like this out of hundreds of orders. There's always an extra inch or 3 of room where they fold and tape the end of the bag.
It's the lack of any evidence that the box had ever been taped in the normal way that makes it really, extra odd. It has just 5 of these skinny fiberglass tape "butterfly bandages" around the seams.
These are leadless IC's, and I don't really expect there to be any damage, so I am not going to be contacting Mouser. I need these now, and that is that.
The most likely thing I think is they just happened to be bagged super tight, then the box got damaged before it was taped, while at Mouser. Then someone looked inside and said "well, they're probably still fine." And then they taped the damaged box up, funny. Maybe it was right before pickup, after shipping confirmation had already been sent. And they rightly figured, better to send them out on time and fix it if the customer has a problem. Maybe they even had the time to take them out of the bag for a better look and re-label a new bag after the tubes had been "shortened"... explaining the OJ glove fit.
If I don't see any IC fragments, I'll probably just use them all. If my app were more safety critical, I might discard the ones near the bends, at least, if not suffer a delay to get them all replaced. I think I'll try to sort those chips at the bends for a closer inspection and/or to save them for deep inventory/emergency reserve.
