Because of the natural durability of leather products, they often endure for decades. Full-grain leathers are made from the higher layer of the skin and have a natural grain of the hide. Although they may appear harsh, you may always oil them if necessary. Even though leather goods are not valued based on their durability, full-grain leathers are the most expensive. The finest leathers absorb oils and become more beautiful as a result. It may also be handed down from generation to generation.
