This mug is just great. A real superlative, not least in the cupboard, because it is the first mug that can be stacked. The material insulates excellently and keeps the drinks at the right temperature for longer. It is extremely robust and therefore particularly practical for daily use - and of course for all outdoor activities, travelling and sports. The rounded shape makes it a real treat for the hand. The original mug is made of environmentally friendly, recyclable plastic, making it particularly light and durable and guaranteed BPA-free. During processing, it uses up to 90% less energy than a ceramic or porcelain cup. Our favourite mug.
