Thank you for viewing. **"Dark Green (Deep Green)"**, evoking the silence and intelligence of a deep forest. This is a handmade A5-size travel notebook, luxuriously crafted from the finest top-layer cowhide. 【A lifelong companion that fits into the adult daily life】 The more you use it, the more it shines, growing into a notebook unique to you... Why not enjoy the luxury of "writing" that can only be experienced in the digital age, with this notebook? ■ Flavorful "Crazy Horse Leather" The material uses high-quality cowhide carefully tanned with plant-derived tannins from Thailand. The surface is specially oil-processed (Crazy Horse processing), and it features a smooth, matte texture. You can fully enjoy the "pull-up effect" where the color lightens when the leather is bent due to the movement of oil, and the aging process where small scratches blend in with use, creating a beautiful luster (patina). ■ Intellectual and Retro "Vintage Green" The calm, deep green color resembles an antique appearance like an old Western book. In business settings, it gives an "intellectual and calm impression," and in private, it creates a relaxing time. With use, it will evolve into a deeper, more subdued color with a hint of black. ■ Highly versatile "A5 size" & "Refill replacement type" It has a generous writing space and is an exquisite size (15cm x 22.5cm) that is easy to carry. This time, we will deliver a set of **"3 dedicated refills (inner cores)"** so you can use it immediately upon arrival. It has a simple structure that is secured with a rubber band, so after you have used them up, you can replace them with commercially available A5-size refills and use the cover for a long time. 【Product Specifications】 • Size: 22.5cm (height) x 15cm (width) (equivalent to A5 size) • Material: Natural cowhide (top layer, vegetable-tanned, Crazy Horse processed) • Color: Dark Green (Deep Green / Vintage Green) • Specifications: Rubber band closure • Accessories: 3 notebook refills • Condition: New, unused 【About the characteristics of leather products】 Because natural leather is used and handmade, there may be wrinkles, scratches, and blood vessel marks that the cow originally had.
