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 provides excellent thermal properties, maintaining the temperature of your favorite drink for up to 5 hours or keeping it chilled for 10 hours. The two-part lid offers flexible functionality. The lower part has a pleasant drinking surface and can be covered with the upper part for hygienic use. The lid's construction ensures that the thermal mug and thermos are 100% leak-proof, while offering 360° drinking access.
