The silicone infuser mug makes brewing loose leaf tea a snap. The infuser is made of 18/8 stainless steel and is laser cut with fine perforations to allow perfect straining of the smallest leaves and sediment. The cup is equipped with a 'stay cool' silicone handle and lid and doubles as a coaster.
Ceramic, stainless steel, and silicone.
Dishwasher safe. The cup itself can be put in the microwave. But not the infuser.
