With the volume that ship from California (main US warehouse) they are lot sampled. A lot of times we have to add things to the box as well. They are in the same Everlast box from the factory. If we have a problem area, we have wrapped units is bubble plastic.

All Everlast distributors (smaller volumes), far as I know, open each unit and inspect them. Everlast Canada (Duncan) and Everlast Alaska (Ray) actually they fire units up as well.
