50-9 1/2″ x 20″ Brodart Fold-On Book Jacket Covers – Center-Loading, Adjustable, Clear Mylar

The length is a bit shorter than I would have liked—the ends of my book covers are all hanging out for the most part—but overall these are exactly what I’ve been looking for to cover my hardcover books. The ends are still protected by being tucked inward and the most important part, the outer cover, is protected.Application is extremely easy (take book cover off book, fold into the plastic Brodart sleeve, put back around book), and the material quality is excellent. I happily recommend these if you’re looking for extra protection for your hardcovers!Note that the height is not really adjustable. These are for books that are ~9-9 1/2 inches tall. You would have to bend the plastic down and crease it to fit shorter books.
