I bought a couple of them. They are well made, covered with moleskin and have a map of middle earth and a nice gold dragon on the cover. They have an elastic strap that holds them closed when not in use.
They are small, about the size of the palm of your hand, with 192 pages. So I guess they're Hobbit-sized!
I got the un-ruled ones so people don't have to worry about writing on the lines. The ruled ones have a different image on the cover.
