Good quality wallets are almost always made from full grain leather. Full grain leather is tough, resists wear & tear more than other grades of leather, and develops a beautiful patina when used for a long time. On the other hand, a genuine leather wallet might not last very long.
Leather is highly durable, which can last for decades with proper care. It does not wear or fade quickly. And it's a versatile material that is perfect for making bags, wallets, belts, and footwear. Leather softens and becomes more flexible as it ages, also easy to clean and maintain because it is water-resistant.
