Although the tea cups come in different shapes, all of them can be hung on the wall of the cup. A fun tea diffuser that will make you love drinking tea. Easy to use: just open the silicone strainer, put in the tea leaves, fruit tea, tea flavored or whatever you want to prepare, close the lid and place everything in the cup with water.
