This is 10mm or 3/8″ (the recommended thickness by the Marble Institute of America for natural Stone) and 42 pieces to a sheet giving you a complete square foot. You will notice competitors, will a) Make it thinner or b) Make it smaller or c) Both. It is terrible and no one needs to confuse the consumer to make a sale.
