Features: Five sachets, each containing 2 grams of desiccant Absorb moisture in humid conditions. Recommended for use in all Aquapac cases. In humid climates, moisture in the air inside the case can condense into water droplets. A sachet of desiccant will absorb any such moisture, keeping the contents completely dry. We strongly suggest its use with all Aquapac cases. Desiccant sachets are highly absorbent and environmentally-friendly.
