This tumbler helps you enjoy your favorite beverage at the perfect temperature. Its double-insulated walls help retain your drinks soothingly hot or refreshingly cold, while the stainless steel, stemless design makes for incredible durability and ease of use.  The artwork features Jael, the courageous wife of Heber the Kenite who lured Sisera to his death with a warm drink.  Thus the humorous play on words, "Drink Up, but Don't Get Hammered".
