No teapot needed here! This infuser turns your mug into a one-stop brewer. Extra fine stainless steel mesh enables excellent water flow with plenty of room for tea leaves and botanicals to unfurl and expand. To stop infusing, rest v-shaped clip on a mug rim to allow tea to drain. Silicone rim insulates to help retain temperature while keeping the infuser cool to the touch. When inverted, the ceramic lid can be used to rest/hold infuser.
