"Opaque dice are made of a particularly dense material for a better feel when rolling. This material also allows for flatter faces and sharper edges. The wide variety of colors is also very consistent so that an opaque Chessex die from years ago will match those available today. These dice are very economical, at a fraction of the cost of others. This set contains one d20, one d12, two d10 (00-90 and 0-9), one d8, one d6, and one d4."
