Vapor Corrosion Inhibitors (VCI)
The most advanced liners utilize Vapor Corrosion Inhibitor (VCI) technology. These liners are impregnated with specialized compounds that slowly release a sub-microscopic protective layer that bonds directly to the metal surfaces within the drawer.
This invisible barrier prevents oxygen and moisture from reacting with the steel. For owners of precision calipers, micrometers, and high-carbon steel blades, VCI protection is a mandatory feature to prevent pitting and oxidation during storage.
