This 2" mesh ball infuser is made with grade 18/8 stainless steel and it is perfect for brewing a single cup of tea in a mug or a few cups of tea in a teapot. By inserting the desired amount of loose leaf tea into the ball and closing the clasp, you will be able to brew the best tea every time. Simply insert the ball into your tea mug or tea pot and pour water over the ball. The fine mesh prevents any tea leaves from escaping into your mug while also allowing the leaves to fully unfurl to yield the most flavourful tea. Upon completion of the desired steeping time, the ball should be removed, emptied, and rinsed with water to be ready for it's next cup.
