A method of directly bonding two pieces of leather without using inner materials is employed, resulting in high durability and robustness. While it may feel somewhat stiff when first used, it will soften with a few uses, providing a comfortable feel. You will also experience tactile and auditory feedback (the sound of the leather compressing, "squeak") when opening and closing. About Italian Special Brushed Vintage Leather: Special Frost Vintage Leather is made using traditional barrel tanning techniques with over 1,000 years of history. This technique uses no chemicals, only vegetable tannins and animal fats, and coats the leather surface over several months. As a result, the Italian Special Effect Brushed Vintage Leather has a strong, elegant texture, is rich in oil, and has a lightly polished surface. It will gain luster over time, developing a smooth, waxy flavor. Not m+.
