A5 Organisers System Notebook with Leather Hinge - Brown

This is a system notebook that opens with a hinge crafted from leather and thread. It is an A5 size (paper size is 210 x 148 mm, 6-hole type). The distinctive leather hinge is the result of our proprietary research and manufacturing methods. It involves intricate cutting and shaping, followed by painstakingly shaving each tooth to achieve a precise interlocking fit. The benefits of this hinge extend beyond its unique appearance. It opens perfectly flat, preventing the pages from unexpectedly closing due to creasing. Furthermore, the areas that flex during opening and closing will not degrade excessively over time. The material is a thick, 2mm vegetable-tanned cowhide, renowned for developing a beautiful patina as it ages. The smooth, lustrous grain is characteristic of aniline-dyed leather. The A5 size is the largest and is often considered ideal for business use. The ring diameter is 15mm, comfortably accommodating approximately 100 sheets of dedicated paper. We've included 50 sheets of our personal favorite, "Étranger di costarica Memory Fill A5 RF-G-01" with a 5mm grid, to ensure that first-time users can begin immediately, and experienced users can make the most of their purchase without unnecessary additions. We hope you will personalize your notebook by combining it freely with the wide variety of commercially available paper, diaries, indexes, and clear pockets. For maintenance, please use a delicate cream sparingly. As this item experiences less stress than bags or shoes, the natural oils from your hands are usually sufficient. In fact, be cautious of over-applying leather creams or oils. The metal rings are designed with screws for easy replacement should they ever break. We hope you enjoy the rich transformation this notebook undergoes with age. 【About Tochigi Leather】 This Tochigi leather retains the natural markings of the animal, such as pores and blood vessel lines, and carries a faint, pleasant aroma when brought close.

In such cases, we will inform you of the estimated production time for a new item and inquire about your preference for cancellation. *The leather used is not coated with pigments on the grain surface, so it may exhibit color variations, blood vessel lines, growth marks (natural wrinkles), scratches, insect bite marks, blackening from residual iron, or traces of hair follicles. We use natural or aniline-finished leather among vegetable-tanned cowhides, which prominently display these characteristics unique to natural leather. *The color of the posted images may differ depending on the lighting conditions at the time of photography and the display settings of your device. *As each item is handmade and unique, there may be slight variations in shape, as well as minor, unnoticeable scratches or color irregularities.
