Bright Ideas Clear PVC Adjustable Book Covers – 37.5 x 20.2cm, 130 Micron, Box of 50 Covers. Sturdy Book Covers. Easy to Clean Plastic and Wipeable Made to Protect School Exercise Books. BI9006.

Just perfect for standard sized paper backs ! When I gift a paperback , I cover it with one of this covers . The are quick fitted and take good care of my books . The rounded edges don’t poke in my hand when I search for my book in my huge tote bag + the prevent the fine corners of being “dog eared “

These are great value for money and perfect for modern paperback books. However, I was specifically looking for 37.5 X 18.0 to cover old size books.

They might not make the contents of a book any clearer, but they are fantastic for protecting and showing off a paperback's cover. Fitting them, is straight forward and it all works well. Books feel more substantial with these little wonders, which are thick enough to protect well, but still easy to work with. They won't work with all paperbacks mind. You're looking at just your standard sized paperback. Anything, even just a tad taller, won't fit (though it will take all sorts of thickness), whilst anything much smaller, may be protected, but looks a bit silly. Even though this leaves a decent proportion of paperbacks these won't size with, they do such a good job with the rest, and work out at such good value, that they do thoroughly deserve their five stars.

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.

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!

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.
