A stylish bottle that combines the functions of a teapot and a cup, and promises a delicious tea time. Moreover, it has a slim size of 130ml capacity and a diameter of 47mm, and the main body weighs about 190g, so you can put it in your bag and take it with you every day. 3 easy steps to use. 1. Open the lid on the filter side and add an appropriate amount of your favorite tea leaves. 2. Flip the bottle upside down and add hot water from the other side of the tea leaves. 3. When the tea is extracted, turn it upside down again and twist the bottle to complete. The main body is with silicone rubber so that you can hold it even if you put hot water in it. What's even nicer is that you can add more hot water by opening the tea leaf valve, so you can enjoy the second cup. You can also enjoy cold brew (depending on the tea leaves), so it can be used in all seasons. I'm glad that it has a window that lets you know how much is left. Easy to clean, the tea leaf filter is a punching type that prevents the leaves from getting caught. It's nice to be able to enjoy freshly brewed tea outside.
