Teapot includes a 100% stainless steel tea infuser to brew that perfect cup: The infuser is generously sized so that the tea leaves have room to expand. Thanks to a high-tech manufacturing process, the infuser's micro-etched design allows for perfect flavor release while holding back sediment. This is not your Grandma's mesh filter anymore! No residue build- up, it's easy to clean, and dishwasher safe. Made by Frieling.
