The stainless steel tea infuser is approximately 2.5" wide from handle to spout (1.25" inside), holds about 3 teaspoons of tea, and the chain is 5.5" long including the beads and charm. Just twist off the top and fill it with your favorite loose leaf tea, twist the top closed to secure it, and steep in your mug or tea cup. It comes with a round tray to put the dripping infuser on when you're done steeping so there is no mess.
Please wash or rinse and dry by hand, and do not put in the dishwasher. Please note that this does not come with tea.
