HumiSafe® Moisture Protection System = barrier bag + silica gel DriBox™ - 4 combination sets

The DriBox™ system features a refillable clear plastic desiccant container box and indicating silica gel beads. Features StayDry™ indicating silica gel beads - a granular, porous form of silicon dioxide made synthetically from sodium silicate. Silica gel protects cameras, lenses, computer parts, binoculars, and other items against fungus, mold, and corrosion. These Silica gel beads have had a moisture sensitive color added with cobalt chloride to show progression from dry blue, to wet pink. It is used as a desiccant to remove water vapor via ADSORPTION onto its surface. Rigid plastic container can be opened for fresh desiccant refills. Pair with a set of 4 PAKVF4C Mylarfoil high barrier bags to get the most out of your moisture protection SOP.

Applications: Great for storing specialized electronics, armorments, rifles, home safes, and other items. Also can be refilled or renewed by heating Dribox™ in a microwave oven for 15-20 second bursts until color turns from pink to blue (For conventional ovens: 3 hours at 240°F). Will dry entire contents of this bag in about 48 hours.
