Have you checked out "Beyond Your Backdoor"? It's a nature store and a new division of Lesser Jewellers.
This magnetic shiny bolt is a very sneaky geocache container. The bolt is hollowed out to hold a log sheet. The magnet is secured in the nut.
When threaded together this looks like a realistic new bolt. The strong magnet will hold it firmly in place and the rubber seal keeps the log sheet dry. Attach this to anything metal and watch those favourite points accumulate! Two Rite in the Rain log sheets are included.
Remember to follow Geocaching.com regulations and respect private property when hiding caches!
