Transparent sturdy plastic vials with a snap close lid. These vials are useful for containing a log roll in a small custom-made container but are not likely to be sturdy enough to be a geocache on their own.
Often you see them called a "pico" cache or micro cache. This style is similar in size to a standard bison. They can take the same log as a standard sized bison micro or a scuba style log.
Containers don't tend to be resistant to UV (ultraviolet) exposure for very long so ensure the container is protected from sun exposure for the longevity of the cache.
