This traditional Staunton-styled set is constructed of stout marble and resin: the pieces are light enough to be easily moved during games yet solid and stable enough to stay put in wind and inclement weather, and unlike many flimsy chess sets, the board is a full 1-inch thick. Frost-proof, the pieces and board resist cracking, fading, and erosion for years of outdoor play (the handsome set can also be used indoors).
