The FRANKENSTEIN III notebook by iberi K features a high-quality leather cover in dark brown and green tones, crafted from "Crazy Horse" leather. This type of leather is recognized for its durability and its waxed (non-glossy) finish, which over time develops a unique patina that gives it an unmistakable character. The two leather tones that make up the cover have been hand-stitched, ensuring a piece with a high level of quality and precision.

The notebook includes two inserts, each with thirty pages of 80g paper, artisanally aged with coffee for an aged touch. The covers of the inserts are made from recycled Kraft paper, completing a fully handcrafted design.
