Zerust VC2-2 NoRust Vapor Capsule - Pack of 2 - Made in USA

Been using these for years in my moderately large safe (60"x42"x27"). Never had ANY rust. They essentially release a vapor that inhibits rust but doesn't leave a coating on anything (I can't feel anything). You wouldn't know they are there if you don't see them. I write the date with a sharpie so I know when to replace them. Cheapest insurance you can have for your collection.

I've used these before work great for toolboxes or any other equipment that is out in the garage or shed that you don't want to rust.

Works great in the safe.

These are placed in every gun case I own, never a rust issue even in Florida Humid weather!

It's kind of like garlic for vampires. If it's working, you really don't know that it's working. LOL But, I guess that it's good/cheap insurance.

Great product, been using VC capsules for years and have never experienced any corrosion on any metal objects...I highly recommend using these 9or similar products) in any gun safe or tool drawer...

I had a pair of pliers with minor rust which I cleaned and treated with oil. Put this in a small toolbox with it and it still rusted far worse than before.

great product for extra insurance to keep rust out. Been using zrust in fishing tackle boxes for years and my gun safes
