i've been using molsekine books for years. i love them, but they always seemed a bit too small. i was really excited when i ran across this! it's A4 aka close to 8.5"x11".  some people don't like moleskine books because they don't lay flat when you open them. this one isn't like that it all. it opens and lays flat easily. it has all the great moleskine features, and more. i'm happy i bought it, i use it everyday and when i fill it up, i will definitely buy another.
