I like to carry a notebook around for ...notes, lists, and things— normal stuff. However, I find myself feeling selective when I want to write in my Traveler's Passport or something with a 'purpose' I've contrived in my mind.
This is perfectly sized at A6 to fit in my pockets, not too big that it's bulky, and the paper is perfectly fine for fountain pens I would use for tasks like these- although I tend to get some ghosting.
There is no closing string to keep it closed like on their A5s, but there are page numbers, which is something I like.
Also, there are perforated pages, so I can easily and cleanly remove something if needed.
I'm a fan.
