Prototype design. I have not had this design fabricated but it is the same as the ring holder dice cube design also available in the store except without the number holes. The ring holder dice cube has been successfully fabricated.
The container has a centrally located screw mechanism to attach the cover to the container. The screw mechanism is based on the always-popular and proven stamp roll holder design also available in this store. The diameter of the central post is set at 0.5 inches (12.7 mm) which means ring sizes of approximately 1.75 or larger can fit in this container. Due to the larger size of this container the walls are approximately twice as thick as those of other ring holder boxes in this store. This protects the walls from bowing and makes the container much more robust.
