Use with loose herbs or teas. Fill half full to allow the leaves to expand. Tea ball has a chain with clip to be hung on the cup. Just remove when steeped to desired strength. Easy to open and close, but secure enough to prevent loose tea from escaping. Dishwasher safe. Choose from 2 sizes: 2 inch or 3 inch. The 2" is ideal for most cups, whereas the 3" is great for bigger pitchers or even bath treatments.
