A tiny dark “witch’s book” (size 6 × 4.5 cm) with mixed‑media covers. It is bound with coffee‑tinted paper and lightly scented with patchouli oil. Inside are about 50 pages with various stains, splatters, and other aging effects, yet they remain light enough to write on.

The mystical notebook’s cover features a portrait of a mysterious woman and a little secret key. The book can be tied closed with leather cords. The bookmark is also adorned with a small key.
