They have long been used as sterile containers for First Aid Kits
Of course people use them for magazine storage as well
They have also been used to store valuables
Because they are airtight, they found a use as humidors for cigars
People have used them as saddle bags for motorcycles
As a center console for your Jeep
How about as a portable MP3 speaker box?
A bug-out Radio?
As a lamp base
As a shadow box?
What a minute, a camp stove? Really?
They have been used to hide Geo-caches......
Just be advised, they are not rust proof. This poor High Standard Sentinel will never be the same
