A transparent plastic tube packaging container includes an outer tube having an inner tube of smaller diameter mounted therein to form a space or air gap on all sides between the inner tube and the outer tube. A first end plug closes a bottom of the inner tube and is fitted within the outer tube adjacent the bottom thereof and a second plug closes a top of the inner tube and is fitted within the outer tube adjacent the top of the tube. Hubs extending inwardly from the end plugs hold magnets placed in the inner tube in a position spaced from the top and the bottom of the inner tube.
