IT was actually given to me by a geologist who worked for the Army Corp of Engineers...however, it is really just one of those insulated "floating" thingies that boating people keep their keys in. (believe me, if you have ANY
sense of boat safety, and you don't have a spare set of keys inside a floating receptacle like this, I won't go out on the ocean with ya.

So you can just google floating key container or floating key holder, I did and came up with these; they're about $2.00 or so. I use them for a lot of other things, too!
