The Tube-A-Ton is a multipurpose tool built to hold all kinds of small kits including batteries, geo-caching, pet identification, emergency cash stash, water purification tablets, storm-proof matches, cotton balls for fire starting, pills, thread, etc.

One side of the Tube-A-Ton is a battery locker that fits AA batteries perfectly. Each side has a tight o-ring seal to prevent exposure to moisture in the toughest conditions. Has a large loophole for attaching lanyards and split rings for EDC.
