Leather raw material quality plays a crucial role in the durability and appearance of leather products. High-quality leather is sourced from carefully selected animal hides such as cow, buffalo, goat, or sheep, chosen for their strength, natural grain, and minimal defects. The raw hides are properly preserved and processed through advanced tanning methods such as vegetable tanning, chrome tanning, or semi-vegetable tanning to ensure softness, flexibility, and long-lasting performance. Premium leather retains its natural grain structure, offers excellent tensile strength, breathability, and develops a rich texture over time, making it suitable for high-end leather goods and professional applications.
