The Chessex Mini Gemini 7-Die Set in Black-Purple/Gold (CHX20640) features miniature-sized, swirling black and purple marbled dice with crisp gold numbering. This 7-die RPG set (d4-d20) is roughly 30-40% smaller than standard, making them ideal for portability or smaller play spaces. They are often black-light reactive and come in a clear, small storage container.
