Zerust 11327 Anti-Rust And Corrosion Vapor Capsules, 4-Pack

I put 2 of these in my smaller safes, and 4 of them in the long rifle safes. I have been using this for years for my gun collection. I do not have to oil my guns as often. There has never been any rust on any of my guns. I replace them once a year. I highly recommend them!

Just what I wanted at a good price!

Prevention of rust in gun safe. No recharging, replace on a schedule

One set I received had labels to attach for when you installed them, the other from another vendor did not. I thought they'd be larger but so far so good. I might update this review after the warm, humid weather comes. I use these in a basement tool box and one out in my garage as well.

A bit high priced, but good for long term storage in damp areas.

My tools are in a cabinet in the garage where the humidity can get rather high for much of the year. These seem to minimize the corrosion in my tools. I don't have much of a control group for the data, but the one tool box I have that didn't have one of these rust inhibitors inside did have rusty screwdrivers and pliers when I opened it- none of that in my tool cabinet so I'm a believer that it helps. Would definitely buy again.

Easy to use. Really protects

This product will protect firearms from corrosion. Make sure you date the outside so you know when to change.
