Inspired by the famous agates of Lake Superior, these 100% post-consumer recycled dice are part of our effort to keep plastic waste from polluting the waters of Gichigami. Replay Workshop collects plastic that would otherwise go to our local landfill, such as the pharmacy vials that are the primary ingredient in Superior Agate Swirl dice. Other colors of plastic added to the transparent amber results in an intriguing agate-like finish. These oversized d10 dice are individually injection molded, painted, and buffed in our shop near the western tip of Lake Superior. Each set contains a 1s die numbered 0-9, and a 10s die numbered 00-90. This product is part of the Replay Workshop line from Atlas Games, making quality tabletop game accessories in the USA from recycled plastic.
