Premium Silicone Top: Made of high quality food grade silicone that meets FDA standards, BPA free, healthy and durable. Heat resistant up to 480 F. Good performance: our tea bags are specially designed for tea leaves; the particles of tea leaves won't leak out and get into your tea. They also won't release other flavors but the small suggestive of tea. Excellent designed: just 3 pieces, the transparent body let you see your tea leaf weight more clearly; the rope will fix your tea bag to the edge of the cup and easy to remove; and the bottom cover is easy to open or close to put in or pour out your tea leaves. Easy to clean: after use, throw the leash away, just rinse it in warm soapy water or toss it in your dishwasher; no spot will be left on the surface. Reusable: The tiny holes reduce unwanted leaves floating around in your cup, allow water to move through the tea leaves, but keep most of them in the bags, and won't leave any taste behind except the enticing little tea. /p>
