I bought for my dad, is what kind of insulation cup is better, can make tea, and tea, like the taste of each are different.
Use insulation cup to make tea effect is not very good because of the effect of tea has a lot of, has lost function. If you buy a vacuum cup, suggest you buy a thermal insulation cup (bordeaux red)
Vacuum cup of tea is not good, will smother the tea yellow if office, an elegant cup is good, suitable for bubble tea and oolong tea, a habit is to see region, and the pursuit of efficiency
Temperature is not suitable for making tea And to choose to suit different tea tea set
