The Time Capsule is a consumer storage device inspired by the NASA Biological Research In Canisters (BRIC4) hardware which was designed to provide a storage container for space flight. These jars are completely air and water tight and resist normal pressurization. The wide, thick screw thread and the double thick rubber g-spec o-ring guarantee that materials you place inside this container are well protected from outside elements while also sealing odors inside, making these containers smell proof. It is made of a super strong advanced polymer that is reinforced and UV resistant.
