Original government use unknown. We have a limited overrun of "Delrin® Storage Capsule (Waterproof)". We are not quite sure what Uncle Sam is putting in his lightweight capsules, but we are using ours to keep small important items close and secure. Brand new, never used overrun from government contract.
Possible uses include:
Use responsibly and due to the nature of this item, it is not returnable for obvious sanitation reasons.
Waterproof, fits easily onto keychain, or into a pack or organizer (I use mine with a split ring), super strong and light.
