Choose a Family Time Capsule when your project is small. In the Family Category you'll find stainless steel cylinders ranging in size from 3.5" x 11.75" to 6" x 24". If the time capsule comes with a sealant kit, you can bury these outside if you wish. Complete instructions give you plenty of guidance. We placed some of our capsules in the Groundbreaking Time Capsule category, and the Archive Box Time Capsules are our capped style boxes. You can order any in-stock time capsule in an Easy Project Package that includes a preservation kit and outdoor plaque. And some of our bolted time capsules may be available as special order boxes.
