How can leather be cared for and maintained to ensure its longevity?

Leather can be damaged by direct sunlight or heat sources like radiators, so it's best to keep it away from these sources if possible. Don't use harsh chemicals like bleach or ammonia to clean leather, as they can damage the surface. Stick to mild soap and water or a leather cleaner specifically designed for the material. When not in use, store leather items in a cool, dry place away from direct sunlight. Avoid folding men's toiletry bag or creasing the leather, as this can cause permanent damage.

Seek professional help: If your leather item is particularly valuable or delicate, consider taking it to a professional leather cleaner or restorer for proper care of leather satchel bag.
