This modern type of teapot makes it easier to prepare loose tea and can bring this great drink to more people. The teapot is made up of a glass tube-shaped teapot itself, in which is a openable/closable plastic strainer.
Loose tea is prepared in it and poured over suitably cooled hot water. The tea is allowed to steep in the water for the required time and then a simple lever mechanism opens the bottom of the strainer and the final tea flows into the glass part. This serves as a tea pourer = from it you can already spill the tea into the prepared cups and enjoy.
