This tea strainer is used if you put loose tea directly in your teapot. Hold the strainer over your cup and pour the tea through to strain any leaves that escape the pot. It can also be used to sift or push the matcha through with matcha scoop/spoon into a bowl or cup before adding the water. This removes the likelihood of clumps in your brewed matcha.
