Nano cache

A nano-cache is an extremely small micro-cache. A nano-cache is generally much smaller than a 35mm film canister, and has room for only a custom-fit log sheet. Examples include:

• bison tubes
• blinkers
• contact lens cases
• memory card cases
• breath strip containers

There is no official nano-cache size at Geocaching.com. Some cache owners list nano-caches as micro-caches. Others list nano-caches as an unknown size, and explain the nature of the container in the cache description. Many nano caches will magnetically attach to metal objects like stop signs or benches.
