This unique infuser makes steeping tea fun! Makes a perfect cup every time! This has a patented gravity filtering system which filters out the tea leaves. Simply add your tea, pour in hot water, let the tea steep. Then place this steeper on top of your cup and watch the tea release into your cup while the leaves remain in the steeper. Once the steeper is lifted from your cup, the tea stops pouring out. Easy to clean by hand or place entire unit on the top rack of your dishwasher.
