Made of 18/10 stainless steel, this closable mesh infuser is made for infusing loose leaf teas into hot water without mess. Unlike a strainer, it lets you decide how long to let your tea steep, giving you control over its taste and strength. It comes in two different sizes—4cm for individual mugs and 7.5cm for teapots. You can also use it for infusing fresh herbs and spices into soups, stews, and other meals. The chain has a hook attached to the end for easy removal.
