Kay Bojesen mug steel from Kay Bojesen is made of stainless steel. As a functionalist, Kay Bojesen was convinced that it was never too early to come into contact with well-designed tableware. This was also the philosophy behind the steel mug, which was originally made for children. The handle is designed so that small hands can easily grip and hold the mug. The mug is equally fantastic and practical for adults to use for cold drinks on picnics, hikes or boat trips.
