These caches are approx. 2" long including the ring. Light, paintable, and versatile, they can be hidden anywhere! They are great for Urban Micro caches. They even include a separate micro container that you can use in the cache or as a separate cache by itself.
These containers are similar to the bison capsule containers.
We also offer extra replacement o-rings. (thicker and more durable) as well as waterproof logsheets!
