316 Stainless Steel Thermos Cup, Large Capacity, Men’s, Cold Retention, Tea Water Separation, Tea Infusing Cup, Portable, Car-friendly, Outdoor Kettle

This design is a major highlight of the thermos cup for making tea. It usually adopts a double-layer cup wall structure. The inner cup wall holds water, while the outer cup wall holds tea leaves, with a fine filter in between. When boiling water is poured in, the hot water fully contacts the tea leaves outside the inner cup wall, allowing the nutrients and aroma of the tea leaves to be released. Meanwhile, the tea dregs are blocked by the filter in the outer cup wall and will not mix into the tea water, enabling people to enjoy the rich and fragrant tea without worrying about getting tea dregs.
