This season each event is part of an alpha series of titles highlighting a term used in Geocaching. Today’s event is brought to you by the letter “N” for Nano.

Magnetic nanos are some of the smallest cache containers. I’ve included information and links directly from Geocaching.com specifically about cache sizes.
These tiny metal containers make great nanos—the smallest type of micro cache. They stick to magnetic surfaces and tend to be waterproof
5.5. Cache containers explained
The popularity and longevity of a geocache often depends on the cache container. Before you choose a container, check out these helpful resources:
6.12. Cache container sizes
Geocaches come in all shapes and sizes. The definitions below can help you choose the correct size for your cache. The names of container sizes differ slightly between our website and app, but the definitions are the same.
Micro (XS)
Micro containers are less than 100 milliliters. They’re about the size of a film canister, or smaller. They can hold a tiny logbook or log sheet. If a micro cache is less than 10 milliliters, it’s often called a nano cache.
Small (S)
Small containers are 100 milliliters to 1 liter. They’re about the size of an apple. They can hold a small logbook and trade items.
Regular (M)
Regular containers are 1 to 20 liters. They’re about the size of a shoebox. Many of these caches are ammo cans.
Large (L)
Large containers are more than 20 liters. They're larger than a shoebox. Buckets, bins, or even railroad freight cars can be large containers.
Other (--)
Some containers just don't fit into size categories, like a magnetic sheet with a logbook attached. See the cache description for more information.
