This is a starter kit for the regular sized Traveler’s notebook blue. The notebook is similar to the A5 size, except it is slimmer in terms of its width. You can easily insert a three-folded A4 sized paper inside. Choose your favorite refills that include notebooks made of various papers, zipper cases and diaries. The more you use the notebook, the more the texture and the taste of the leather cover changes. It will turn into the one and only notebook in the world: your notebook !
