The Carrie collection is a series of reusable thermal mugs and drinking bottles made of high quality stainless steel with a double-walled vacuum construction. This gives excellent thermal properties, holding the temperature of your favorite beverage for up to 5 hours or chilled for 10 hours. The two-piece lid offers flexible functionality. The lower part has a pleasant drinking surface and can be covered with the upper part for hygienic use. The construction of the lid ensures that the thermal mug and Thermos Flask 100% leak-proof while providing 360° drinking access.
