One vial has water inside, and what’s left of a very rusty nail. It had no VCI protection. You can see the grains of iron oxide settled on the bottom, like a sediment. The entire nail is corroded, both above and below the water line.
The other vial has water, a nail, and a small strip of Nox-Rust Vapor Wrapper paper. The nail is still clean, above and below the water. No corrosion. The distinctive ink is still visible on the VCI paper.
