I bought a Handbook watercolor journal 5×8″ because I have seen people use them so of course I had to try it for journaling. I did some tests with ink, pencil and watercolor on the face pages and found:
It does not take wet-in-wet well
Every other medium works great
I like the size and landscape format
It fits in my purse well for those on the spot sketches.
Good way to start 2016!
