If you make tea in the office, you can have the following choices: you can consider the first glass-ceramic cup, because there is no odor. You see, tasting tea is the aroma of tea, and suddenly there is a smell of plastic to spoil it. The second type is stainless steel cup, but drinking tea for a long time will produce a chemical reaction, which is not necessarily particularly good. The third kind is plastic cups, some of which are really heavy. It is recommended not to buy ones with too low price. If you want to buy it, you can refer to the MONJ Health Cup, which is more convenient to carry and resistant to falling. The fourth is the purple sand cup, which can be said to be the most suitable cup for making tea. Many people like drinking tea and raising teapot. Purple sand cups have their own fragrance. However, there are many fake cups now, and they are more expensive, so you should choose them carefully.
