The leather pouch is made of high-quality cowhide, often using vegetable-tanned full-grain leather or nappa leather, depending on the model. To ensure the longevity of the material and the embossing, the pouch should be cleaned regularly with a soft, slightly damp cloth and then treated with a natural leather balm or wax. Avoid harsh household cleaners, excessive heat, and prolonged exposure to moisture to keep the leather supple and prevent it from becoming brittle. When not in use, it is recommended to store the pouch in a breathable dust bag to protect it from dust and light.
