AQUABLUE Bulk Silica Gel:

Silica gel can be used to protect your valuables against moisture related damage by substantially lowering humidity within sealed spaces, and preventing the formation of mold, mildew and rust. It is used in a number of applications, including, but not limited to: storage containers (tool boxes and safes), collectables (stamps, coins), firearms, instruments, stored vehicles, electronics, industrial equipment, or anything else prone to moisture damage.

Silica gel’s extremely high surface area (750 square meters per gram) allows it to adsorb up to 40% of its own weight in moisture at humidity levels of up to 100%.
