Why Must Read Brain Games - Word Fill-In Puzzles?

I do a lot of puzzle books, and I was excited about receiving this one. I have never purchased this brand before, but loved the idea of a spiral bound book. I think the puzzles are great, but I gave it three stars because the paper is so thin. I cannot use a pencil or a regular pen with it. I have to use a very light colored gell pen. I did a few puzzles out of the book, and then put it away. I love the idea of it, and maybe the one I received was a messup. Who knows? I do not plan to purchase from them again in the future.
