Anti-Corrosion 10" x 10" Foam Sheet

Placed in any enclosed space, this 10" × 10" foam sheet provides continuous corrosion protection for up to two years. It gives off a harmless corrosion-inhibiting vapor that forms an invisible crystal barrier on ferrous and non-ferrous metals. It can be cut to fit into a drawer, toolbox, tackle box, etc., and protects a total of 8 cubic feet (1 sq.in. of foam for 138 cu.in. of volume).
