SafePack
I had the chance to play around with this product at work, and cover a few books. Design is really simple. Take the dust jacket off the book, slide into the cover, and fold to fit. The bone folders (real or plastic doesn't really mater) will give the folds a nice sharp look and gives it a solid crease so the jacket cover stays in place better. I like the look of the low-luster myself; the super clear is too shinny for my tastes, but to each their own :). All in all, great easy to use product.
