Multi-purpose popular elegant filter drinking glass tea cup

This product has five Styles and three capacities. They are 500ml, 620ml, 1000ml, straight and drum type respectively. The material is borosilicate glass +PC liner. The liner is the traditional press water outlet pattern, and there is a red button on the lid. We gently press the steel ball inside the liner automatically, so that the water flows into the main cup. There is a snap between the inner container and the main cup, so that we can put the inner container and the cup together, and don't need to take the liner away when we split the tea. And the lid part, we have a spring control, when pouring tea, the lid will not automatically fall, so as to avoid the embarrassment of inner container tea drop.
