Superb, an excellent opportunity to keep your books in great condition. I've been looking for good ones for a while, having had ones that break on first use to ones that ladt a few months. But these ones are the best so far. I've recently done 40 books in the Terry Pratchett edition with the black cover. Not one broke while fixing them on the books & they are a great fit. Only time will tell how they will take care of the book's. But they are of much greater quality than any others I've used. I won't be looking at other options for the foreseeable future.

They are amazing. I bought them to protect the books in my book corner as I’m a primary school teacher and bought the books myself. Now the books will last longer than before.

Perfectly fit for my books. Just the front edges are curved while none of my books are😁It fits the standard size of the book, top to bottom must be sized 19,8cm, max. Thickness won't matter.

Easy to use. Protects my books from damage in my baggage. No more curly corners and the spines also seem to survive as well.

Perfectly covers my smaller and bigger books and prevents my old books from completely disintegrating. I should have bought these years ago!
