Product Description: The medium-size version of our mini ammo cans, this micro geocache measures just 1 1/8 by 3/4 by 3/4 inches high. Made of highly durable plastic, this is a great way to throw a little mystery into your hides. Be sure to post that you are hiding an ammo can in your description but don't choose a size for the container. Everyone will be expecting the standard metal box and will overlook many of the hiding spots where this little trickster can be placed. The container is not waterproof.
