To keep the large brown leather pouch supple and weatherproof in the long term, it should be regularly cleaned of dirt and moisture and then thoroughly dried. For optimal care, it is recommended to apply a thin layer of leather balm, leather grease, or special oils that nourish the material and protect it from drying out. Proper storage in a dark, well-ventilated place at a constant room temperature will also prevent mold growth and fading from UV radiation.
