These titanium nitro pods were designed to be crush proof and will do a great job at protecting whatever you decide to put inside. They can be used to carry small medication, like nitroglycerin pills for the heart, or other small items that need to be kept protected and dry. These are one of the smallest nitroglycerin pill fobs on the market. They use a standard #60 o-ring, which is included. My titanium beaded chains go great with the Nitro Pods.
