To maintain the longevity and natural patina of the vegetable-tanned leather, the belt bag should be regularly dusted with a soft, dry cloth or brush. If needed, the leather can be nourished every three to six months with a colorless leather balm or a beeswax-based conditioner to keep it supple. Should the bag get wet, it is recommended to allow it to air dry slowly at room temperature, avoiding direct heat sources such as radiators, as these can cause the leather to become brittle. A breathable fabric bag is ideal for storage, while harsh cleaning agents and plastic bags should be avoided.
