Our Silica Gel Packets are incredibly useful for adsorbing moisture and prolonging the life of your belongings. Silica Gel desiccant is a non-toxic, non-flammable, and chemically inactive drying agent that adsorbs forty percent of its weight in moisture. Every single gel bead contains millions of surface pores that magically soak up water vapour. The beads adsorb moisture from humidity and create a protective environment of dry air that lengthens the life of your item. Therefore, it removes moisture from many locations and situations ranging from keeping foods like jerky and croutons dry, to reviving your phone from a dreadful drop in water. They're also excellent for preventing rust and condensation so use them with guns and ammunition or with electronics like cameras. Protect your official documents and treasured photos with Silica Gel packets to ensure they will stay dry, despite how humid the storage area gets.
