These durable book corner protectors are made of extremely strong, but flexible, Tyvek® cloth. They are used to wrap around the exposed corners of hard cover books as a way to cover up and repair tears or bends, as well as a way to prevent further damage. They can also be used as soft cover book corner protectors. To apply these corner protecting cloths to your book, simply peel off the release liner and place them on the front of the cover with the open edge facing away from the book. Then, one at a time, fold the edges over and onto the inside of the cover. The strong adhesive creates a firm hold, and you are left with a protective, attractive corner piece. Start protecting your valuable books when you buy Tyvek® corner protection cloth online; several colors options are available.
