These are incredible to hold and look at. They are real carved and etched stone. They are strong and will not break during rolling, that said, we do recommend getting a dice tray to give them a little extra protection from rough surfaces and scratches.
FYI: Slight variations in color, size, and shape are possible because they are all handcrafted. We encourage you to embrace the individual beauty of these dice and enjoy the age-old hand-crafted methodology.
