Tea and coffee can use the same cup?
no problem 1. The glass itself is very safe, so no residue after washing 2. Even mix here, it does not matter. 3. The Hong Kong style milk tea, have a drink called "yuanyang milk tea", actually is the coffee and tea together.
In general do not have what problem Mainly if you want to pay attention to some should be separated And if you want to taste it to buy their favorite professional glass
There is nothing bad to the body health. But remember to use after rinse thoroughly, lest affect the flavor and taste.
