Food Grade Silicone Material: Our tea infusers are made with food grade, non-toxic silicone which is safe for contact with food. They won't leave an aftertaste or an unpleasant odor. More importantly, they won't rust or discolor like a metal tea ball chain. The high temperature resistant tea infuser can withstand temperatures from -40 to 250. Cute and User-Friendly Design: There are many small holes in the silicone tea strainer, which can effectively filter the tea leaves and prevent the tea leaves from leaking into the water. Even if the shapes of the tea cups are different, they all can be hung on the wall of the cup. A fun tea infuser will make you enjoy drinking tea more. Easy to Use: Just open the silicone strainer, put in the tea, fruit tea, flavored tea, or anything you want to brew, put the lid on, then place it in the cup and add water. Then wait for the enjoyment. Easy to Clean: Our tea strainers can even be used in dishwashers. It is easy to rinse the tea out with water and can be reused many times after washing. Convenient Design: It comes with a silicone mat for resting the infuser, which helps keep your countertop dry. Also, it is perfect for large mug cups to steep tea. You will not burn your fingers with hot water when removing the infuser, as it comes with a handle.
