SoilSafe™ was created to solve a practical problem: how to safely and affordably bury a Monster Box quantity of coin tubes without being limited by a narrow four-inch tube.

The result is the SoilSafe™ Monster Box Burial System, built around a six-inch-diameter inner container and designed to accommodate substantial coin collections, precious-metal bullion, and other selected valuables.

Today, the SoilSafe™ system is available in two sizes: MegaTube™ and MonsterTube™.

Both are designed around the same principle: give your stored items a purpose-built enclosure, incorporate multiple protective components, and plan for retrieval from the beginning.

With an ABS inner container, twist-lock sealing lid, included moisture-control accessories, and a double-wall polyethylene outer vault, SoilSafe™ brings several components together in one burial system.

Whether you're storing bullion, building a time capsule, or preparing a geocache, SoilSafe™ offers a dedicated solution for underground storage.

SoilSafe™ — The Monster Box Burial System.

The safest place on earth to hide your treasure is in the earth.
