A note regarding how we grade these boxes
A Super Grade box will be the best quality we can supply, and it will have very minor signs of wear. It will possibly have a minor rust spot or two but no flaking paint. As a used item it will never be pristine or as it was when first manufactured, but the structure, rubber seal and locking mechanism will work as they should.
