Case was broken upon delivery

Lots of rivet nuts that appear to be good quality. However, as can be seen in the first pic, the case dividers are warped and when the item arrived, the orange dividers were out of their slots, thus allowing the rivet nuts to get mixed together. Be prepared to take time to re-sort... First pic is after I already sorted 4 of the largest sizes and shows the warpage. All together, it took over an hour to sort the 860 rivet nuts into their respective sizes. Unfortunately, the case remains warped and the orange dividers still don't stay where they're supposed to. I decided to put the rivet nuts in ZipLocs to prevent their mixing again.
