You'll especially want to watch at the 4:15 mark. It shows "trees" coming off the line (not keshi figure trees though) coming off the line, workers grabbing them, and later, trees/pieces being placed in packaging. Good stuff.

Unfortunately, the video was removed from Youtube! If anyone can track this video down, that would be amazing. It looks like the video might feature some Gundam keshi being made!?
