Browning ZeRust VCI Protectant Capsule

The Browning Gun Safe ZeRust VCI Protectant Capsule is a small capsule that emits an invisible vapor that forms a corrosion and rust resistant barrier on metal surfaces. Volatile Corrosion Inhibitors (VCIs) have been used for years to protect metal parts in industrial and commercial applications. One capsule protects a standard 30 inch wide safe for one year.
