The X17 SuperBuch in the clear format DIN A5 offers plenty of space for ideas and sketches. It is already standard with 3 different inserts (blank, plaid and lined). As a modular notebook, it is possible to update and replace individual documents as required ("Book by Book" system; see "Replenishment Double Pack").
The valuable cover, made of genuine natural leather in various colors, offers durability and gives your ideas and notes a high-quality appearance.
The "natural leather" is vegetatively tanned (i.e., the leather has been exclusively tanned by vegetation).
Intelligently designed notebooks consist of a bonded leather cover, three elastic bands, and three booklet inserts that can be swapped out and refilled. Made in Germany, the bonded leather covers are extremely durable and come with a 17-year guarantee. Each superbook contains one of each of three different refill booklets: lined, blank, and grid. Dot grid and calendar booklets are also available. Each booklet contains 61 pages, each numbered. More information here.
Covers crafted in Germany from Italian bonded leathers; booklets in Norway.
