I have several sales manuals in expanding John Deere binders. They are in very good condition and contain extensive information on attachment bundle numbers as well as weight, pricing. I dont know what size USPS boxes they will fit. They are not light. There is some overlap in information as they are different years. Binders worth my price. You pay shipping or stop by and shop.
