Condensation would be an issue with any of those inexpensive unlined metal “safes” that many people store their firearms in. At least in humid climates. Using some rust preventative on the firearms and/or a dehumidifier should be fine.
The first warning shown in the manual is that this product is not a safe. You have to spend a lot of money to get a real safe and most people settle for these locking cases which are better than nothing.
The second and separate warning is about condensation. I think my not at all cheap safe came with a warning about condensation.
I think giving away these cheap “safes” is a far better and more cost effective safety move than waisting money buying back peoples old worn out extra firearms.
The title to the article makes it appear that the police is the agency that came up with the idea and program. In fact, the article reads made possible by grant funds awarded by the Illinois Department of Commerce and Economic Opportunity, the BPD is offering a free safe to city of Bloomington residents.
Just using the police as a social services agency. Again.
There Ain’t No Such Thing As A Free Lunch…
