This spherical glass 0.5L teapot has an integral infuser basket for use with loose tea and a stainless steel lid. Just pour in the hot water, wait 3-4 min (or to your preferred taste) then press down the plunger. This stops the brewing process so no more stewed tea! It is dishwasher safe and the glass jug can be used in the microwave - just make sure you remove metal the lid and plunger.
