Most drawing books die about 25% through their pages due to my rough handling. The pages stick together, get wet, inks bleed through, the spine gets cracked, the pages bent or torn. None of that has happened with this one. I love the size options, I love the journal-style elastic strap to hold it closed, the high quality hardcover binding, and the detachable pages. The more reckless or crippled you are, the more useful the construction of this book.
