Metal Magnetic Key Holder Cache

Here is the Metal Magnetic Key Holder Cache , its not as common as the plastic kind, I really need to pay more attention when searching for these, as most times they are on guard rails, as this one was, but I'm now so used to these that I really don't look as much as feel for it, one of these times something is gonna bite me! This kind isn't very water proof and tends to rust over a long time, but its still useful, this one seems fairly new.

Yes I rust, but I'm still good, please use me for multi's and guardrails all over the world
