For Basic Style Bibles - This is our lowest cost cover style, and it is a "Turned Edge" style. To see the definition of "Turned Edge" style see FAQ (Frequently Asked Questions) # 23. We use 2 1/2 to 3 ounce leather which is approximately 1/16" thick. Notice it does not have ribs or the title of the book on the spine. We do not offer any gilding of the edges of the book, or personalization of any kind. If you are choosing either a Regular Order or a Rush Order you must get the books to us before we start counting the the time that it takes to complete your order.
