These caps contain Silica gel packs. This material is widely used to absorb moisture off products that must travel by sea. Thus, according to the manufacturer, it is possible to maintain a very low moihumidity rate within the photographic equipment, around 35 to 45%. The humidity that penetrates the lenses is primarily responsible for the appearance of fungus between the lenses, a not so wellknown disease, but the most common one on lenses.
