These are the Official Groundspeak Nano Cache containers. These ones are black. Perfect for your local urban Geocaching experience. A built in magnet makes it easy to hide these cache containers in various settings. Extra log included as well as a gasket to water proof the container.
Bought a couple (one for hiding - 2 for spare) with the intention of painting (have previously used nail polish on these) and deployment but the council has temporarily removed the structure where I had intended to place it. Oh well, I shall wait.
We were please with the price of the nanos and the delivery was fast we expected to wait longer but they arrived only a few days after we ordered the post was fast. We are very pleased with our purchase now to hide some as Hubby has some plans to hid 40 of the little fellows.
