I had been given a quad set several years ago and the edges of the cover were beginning to fray and tear. Not wanting to get a new set of scriptures and lose all of my notes, etc. I purchased a new cover for my book. My book now looks like brand new. The cover is a heavy material and should last as long as the scriptures do. This is a great way to keep your memories and a deal for worn out scriptures that you want to keep. I love it
