Kramstein, a metal stein
A unique glass insert, this vessel holds beverage while keeping your hands warm. Unlike other systems, this stein uses hard metal alloy that is anodized with a durable finish. With the glass sitting inside, the system features ionome bushings between the glass and metal. This allows your beverage to remain nice and cold while your hands stay warm.
