AIRVAULT STORAGE BAGS Long-term firearm protection doesn't get easier than this. Just insert, zip and store your firearm for the ultimate protection. Hoppe's AirVault incorporates VCI technology, a proprietary blend of corrosion inhibitors, woven throughout the interior of the bag. The AirVault protects firearms by creating a molecular barrier against the corrosive effects of moisture, salt, and other contaminants. To store a firearm, simply clean the firearm per the manufacturer's recommendation, place the unloaded firearm in the AirVault bag and securely press zipper closed. Store the firearm in the AirVault in a cool, dry place away from direct sunlight. Ready to use when bag is opened No additional oil needed
