Poštanski sandučić is the Bosnian term for letterbox. Welcome to this new series of London Letterbox caches honouring many different countries and languages around the world. This cache contains a stamp that is not a trade item and should remain with the cache.
From the listed coordinates, you will be hiking west into the field. You can find the final cache coordinates by projecting a waypoint 86 m away, at 249 degrees true.
