The pages fall apart easily. The book wasn’t bound properly at all.
Format: Paperback, Format: Paperback
I’ve just opened this book today. I like how the subject matters are explained and to the point. However, I bought this book new and it is already falling apart from the seams. Whatever they used to bind the pages together is of very poor quality; for that matter I gave it a rating of 3. Wish it was more durable. Now I’m afraid the leaves will all fall out very soon.
