The season when I miss cold tea. You want to make a lot and chill it, but it takes a long time to remove the heat, and if you put it in the refrigerator while it is still hot, other ingredients will be damaged. You can set your own ice pack in the 10 Pocket inside and wrap it around the cold water bottle. With a maximum circumference of 48 cm, it can be used for kettles and small pots.
