A nano maze geocache container, probably the simplest and smallest field puzzle.

The container has the words Official Geocache wrapped around the outside. There is space between the inner and outer parts for an o-ring, 20.5mm X 2mm, to aid in keeping the log sheet dry. The log sheet will need to be a nano log sheet.

There are three locking pins on the outer container.
