This is an official Joani designed Nano Geocache. These “Blinkie” Geocaches are brilliant for Urban Geocaching, as they blend into their surroundings so well. They also have a powerful magnet in the base which greatly increases the potential hiding places. They are tiny, metal screw cap containers. Unlike some versions, the official Joani version has an O-ring to make them watertight. Also included are two waterproof log strips – one spare. They are printed on Rite in the Rain paper, and have a piece of metal attached to them which makes rolling much easier. Only 1.5 cm tall and 1 cm in diameter. Brand new and come in original packaging.
