A container, including a number of angle elements. Each angle element includes a) a horizontal puzzle member including a male knob at one end and a female lock at the other end; and, b) a vertical member including a vertically extending male adjunct at one end thereof and a vertically extending female adjunct at the other end thereof, the vertical member being integrally orthogonally connected to the horizontal puzzle member. The angle elements are configurable, i.e. can be assembled, to form a container by: engagement of the male knobs of the plurality of angle elements with female locks of adjacent angle elements; and, engagement of the vertically extending male adjuncts of the angle elements with female adjuncts of adjacent angle elements. The container may include corner angle elements and additional types of angle elements such as intermediate angle elements, curved angle applications, L-shaped angle elements, and various derivations, including 90 degree applications, obtuse angle applications, and acute angle applications. The angle elements fit together like puzzle pieces.
