Made in the United States, this K2BX 3D printed storage box holds up to ten 5 oz copper rounds in compatible standard capsules. Individual slots keep your rounds upright, separated, and easy to browse, while the black exterior and contrasting K2BX and CU markings complete the look.
Strong magnetic closure. Easy access.
Four corner magnets keep the removable lid firmly seated. The hold is impressive: in our demonstration, we lifted the loaded box by its lid with ten 5 oz rounds inside—50 ounces of coins—and the magnetic closure kept the base attached. Yet the lid remains easy to open when you want to enjoy your collection.
