A palm-sized notebook from LIHIT LAB, about 72 x 55 mm, that fits in a pocket or clips onto a bag as a charm. The rings open all the way, so you can pull pages out, add new ones, or reorder them exactly how you like — it works more like a tiny binder than a notepad. Comes with 30 sheets of 5 mm grid paper and holds up to 40, with a soft polypropylene cover in four colors.
