Picked up this at Distinctly Tea in Waterloo, Ontario, for about $19 USD. It is a single small double-walled glass with a finum infuser basket and cover/lid. It is perfect for a small glass (5 oz. or so) of tea. Seems to be most appropriate for a green tea or oolong tea (certainly not for a tea with milk). The glass remains relatively cool to the touch even after pouring hot water in it. My only complaint is that it’s pretty small, and basically only good for a single cup at a time. The finum brewing basket fits nicely and has a removable ring with handle at the top, and a plastic lid that doubles as a rest for the filter basket after the tea is done steeping. It’s a classy little item… but I have also seen the Bodum version of something like this in single and multiple-glass sets, and might consider that one instead.
