This heat resistant XL tea cup is made of borosilicate glass, which is lead-free and can withstand temperatures from -50℉ to 300℉.
The tea cup is dishwasher safe and comes with a lid and extra fine strainer, conveniently separating the brewing tea leaves from the ready-to-drink tea in the cup. The strainer has a total of 12 thin slits at the bottom to allow water to pass through while keeping tea leaves away.
To clean, simply by hand or put in dishwasher.
While many similar styles of tea cups are small and only fit 1 cup of tea, this one is XL sized and can hold about 15 oz of liquid.
