These are a random assortment of factory second metal dice. These dice have slight scratches/cosmetic imperfections that do not effect rolling. Made with solid zinc and plated with shiny-polished nickel, these 16mm metal dice sets are heavy in your hand, and are built to last. We do recommend rolling any metal dice on padded surfaces like our padded dice trays. This is a full-sized 16mm polyhedral dice set that comes with 7 dice (d4, d6, d8, d10, d10 (00-90), d12, and d20).
