The flip-top tea infuser is leakproof. It is much easier to drink from the ceramic tumbler and even make tea with the advanced design of filter which quickly separates tea-leaves from water. It can also be used as a teapot for outings with friends. The multi-functional lid will make our ceramic tumbler a caring companion to guarantee a healthy, safe, and wonderful lifestyle.
*Please note that this infuser lid only fits with our ceramic travel mugs and it does not fit with our Harmony stainless steel travel mug. Thank you.
