Lustrous is Chessex's pearlescent finish - a soft, shimmery sheen across the surface rather than a flat or speckled texture, closer to how pearl or opal catches light. This set is Purple with gold pips, 12 dice at 16mm, in a display case with foam insert. Reads well as a "premium" or ceremonial set for a Commander deck's dice, a DM's personal set, or anything you want to visually stand apart from your everyday rolling dice.
