Shipped in packs of 10, these tough, transparent mylar covers, 1.5 mils thick, fit dust jackets (aka "book jackets") up to the indicated height on books that are in the usual format (taller than they are wide). For square, or for oblong books (wider than they are tall), a taller cover may be needed to provide enough length to adequately cover the inner flaps. These covers are for dust jackets only; they will not work for books without jackets.
The acid-free paper backing of our dust jacket covers is split in the center, making it easy to insert the dustjacket into the cover and to adjust the height of the top half of the cover, pulling it taut to match the height of the contained dustjacket before creasing the mylar (with any hard smooth object) for a permanent top fold.
Our covers are shipped in sturdy mailing tubes. The price shown for each size is for a pack of 10. You may order any quantity of packs of 10 of each desired size. Please do not try to order partial packs online. You can buy any quantity, even just one cover, in person in the store.
