Our metal carrying cases are designed with multiple purposes in mind.
First, they look great, and make your dice look even better.
Second, they protect your dice. Yes, these dice are resilient, but if you want to preserve them for posterity, you'll want to have some extra protection.
Lastly, they are designed specifically to act as an emergency dice mat. The top and bottom of the case are lined with 2mm dense foam, allowing you to roll directly into the box in the absense of a mat. This protects your playing surface, and in certain circumstances, your dice as well.
Our black cases feature lids that can completely detach, which make them even better as a rolling surface. Because they can detach, they can also be tucked under the case to save space.
