Zerust Rust Prevention Plastabs 1" x 1" - Pack of 20 | Plastabs are Thin, Light, Rigid polyethylene Squares That are Made with Patented Corrosion-Inhibiting Technology

Recommended. I use these inside zip lock bags for long term storage of spare gun parts. So far have had no evidence of rust or corrosion after more than two years.

I will used to protect my spare parts from rust.

I gave four stars and will update when I have used them for a little while. Seem to be good quality and I like the smaller size compared to some brands.

Purchase was fine.

My work area is damp during winter. This product was recommend by a profressional. I add these tiny little squares everywhere. The only issue is you cannot tell when to replace them. The only solution I have found is to write the year on them and then just replace them every yr or two.

I have a relatively humid garage. Upon moving into the new house, I had an issue with some tools rusting.With this product in the tool boxes, I have not had new rust develop.

nice thing to have

The zrust dividers for fishing tackle are larger and I found better to use for storage of items in range bags
