Rarely do you see a product with such versatility that has end of life options like this one. Whether you use the inner or outer chamber for the ice, use it for milk or other beverage storage, for cooling or heating, and now as a straw or tea infuser? How genius can one product be? Apart from its unparalleled functionality, it is beautiful. Your product should be studied in Product Design schools. This is the future of sustainability. Bravo!
