The kit offers excellent long-term protection for firearms, preventing rust and corrosion indefinitely when sealed in the puncture-resistant, moisture-proof bags.
Each Rust-Blox can protect up to 300 cubic inches of space, releasing corrosion-inhibiting vapors that work on steel, aluminum, copper, and brass for at least one year.
The 12 pack includes 12 storage bags and 36 Rust-Blox, made from a combination of polyester, aluminum, and polyethylene, with the bags sized for handguns and rifles.
