The Black Bertha geocache container is approx. 3/4″ tall and 1-1/2″ around at base. Tall enough for the log and maybe a couple of small coins or trade items. Watertight, magnetic (super strong hold), complete with logs in a little zip bag. Comes in black only (not painted), with a camo design label in varying color/styles, medical-grade plastic with snap top. Includes log in little zip bag, it’s ready to hide!
Our favorite way to use these containers is to put a roofing nail in a hollow or deep fork of a tree and then rest the cache on the nail head. It practically disappears! Of course you can also remove the camo label if you want & put them under a public phone stand, park bench, etc.
To test these, we submerged them in water for 24 hours and they remained dry. Of course, they are not meant to be used underwater, but as long as the lid is snapped down securely they should keep your logs safe & dry.
