FOOD GRADE SILICONE MATERIAL Our teapots are made of non-toxic food grade silicone that will not cause any harm when in contact with food, leave no aftertaste or unpleasant odor, and most importantly, will not rust or discolor like a metal tea strainer. The ultra-high temperature resistant tea strainer can withstand temperatures from -40 C to 250 C. CUTE AND USER-FRIENDLY DESIGN The silicone infuser contains many small holes, which can effectively filter tea leaves and prevent tea leaves from getting into the water. Even if the shapes of the teacups are different, they can all be hung on the edge of the cup. An interesting tea diffuser will make you love drinking tea. Easy to use Just open the silicone filter, put in the tea, fruit tea, scented tea or whatever you want to make, put on the lid, put it in the cup and add water. Then wait for the enjoyment. EASY TO CLEAN Our tea strainers can even be used in dishwashers. You can easily rinse the tea with water and can be reused many times after washing. CONVENIENT DESIGN It comes with a silicone mat to place under the infuser to keep your countertop dry. It is also perfect for large cups until the tea has steeped and you will not burn your finger on hot water when removing the infuser as it comes with a long tail as a handle.
