Walkers is the largest Scottish food exporter with as many as 15 factories! The recognizable checkered pattern of Walkers biscuit hides the finest biscuits in the world. The most famous biscuits from the Walkers factory are certainly shortbread biscuits – traditional Scottish biscuits that are made from only four ingredients: flour, butter, sugar and salt. The irresistible taste of real high-quality butter makes these biscuits an irresistible delicacy.
