Query: Good book, not very durable

This is a very good book. It has information about all the 150 pokémon, it has information on how to take acre of them, and it even has a poster! The thing is that it is just not durable! On the fourth day, one page had already fallen down. If they made it in hard over, it would be muh more durable.
