Our perfect mug now comes in crystal-clear glass, right down to its heat and aroma insulating lid. Like the original, it includes a stainless steel infuser that fits right inside, but unlike the original, this mug is totally transparent – so you can check on your loose tea or watch a blooming tea flower. The lid even doubles as a plate for the infuser. Dishwasher safe. Microwave safe, except metal infuser. (capacity: 12oz / 380ml)
