This is a new sealed package in really great shape for being 35+ years old! Shaking the box, you can hear that it?s still loose powder inside, some seems to have settled to the bottom just due to sitting on a shelf. But keep shaking it, and it loosens up more and more. This is the 50oz king size box. From a smoke free home. A little bit of aging to package here and there, but no water or sun damage. See photos.
