Tea Infusers Designed for Medium to Large Leaf Loose Teas, Not suitable for ground Tea or very fine Tea leaves.
 
Simply just pop off the top and spoon your favorite loose tea inside the stainless steel cup.The steel ball's holes aren't designed to brew fine tea leaves.
 
The holes allow the water to move through the tea leaves but keeps most of them in the steel ball and out of your cup so you don't have too many leaves in the bottom of your cup.
Easy to clean: Discard the used leaves and rinse with warm soapy water
