The FRANKENSTEIN notebook by iberi K features a high-quality leather cover in green, brown, and violet tones, crafted from "Crazy Horse" leather. This type of leather, known for its durability and waxed finish (but not glossy), develops a unique patina over time, giving it a special character. The three leather tones that make up the cover have been hand-stitched, ensuring a piece of great quality and attention to detail. The notebook includes two inserts, each with thirty pages of 80g paper, subtly aged with black tea for a vintage touch. The inserts' covers are made from recycled Kraft paper, completing the entirely handcrafted design.
