Chessex: Prism Translucent GM and Beginner Player Polyhedral 7-Die SetOur GM and Beginner Player Polyhedral 7 Die Sets will be a great learning tool for new players unfamiliar with the different shapes of polyhedral dice. The idea behind these sets is that a GM can simply state the color of the die (for example Orange d6) so the new player can easily identify and learn these shapes while roleplaying.
