Rainbow Aegis Dice are a molded acrylic set, electroplated with a durable aluminum shield. This set offers the utility of plastic dice, with the beautiful look and feel of metal dice. We do recommend rolling any metal dice on padded surfaces like our padded dice trays. Each full-sized, 16mm set comes with 7 dice (d4, d6, d8, d10, d10% (00-90), d12, and d20).
