The way mantic pack this from the factory is pretty bad. There is nothing to secure the metal parts from scraping against each other and they just bounce around the whole box. I had several bent and snapped barrels, and other smaller bits. For the bigger parts they use a weird rubbery plastic that is more like a resin. It will have smaller bubbles and issues with large gates all over the place.
Overall it's not worth what you pay and I will be returning my whole order. Nowhere near the alternative companies in quality (GW, Reaper, ect)
