Really nice construction in terms of the material of the paper and notebook itself. The notebook is small enough to easily fit in ones pocket (for mens jeans). Lines and very helpful with straight note-taking and the paper quality is nice (i.e. not to heavy and doesn't tear) and holds up well with several inks I have used (i.e. doesn't seem to bleed through). The bookmark is helpful in knowing where one is currently at, rather than have to bend a corner of the page. I will continue to use this until I finish, and then intend on purchasing additional ones as they make for great note-taking that is portable and non-electronic.
