Is the stirring rod a straw or not?
This concave shape prevents the drinker's lips from being completely tightly wrapped, and absorbs a small amount of air while absorbing coffee, which not only slows down the flow rate of hot drinks, but also plays a role in cooling down.
This kind of straw is specially designed for hot drinks. When you drink a drink with it, it takes a long time to finish smoking, and then the temperature of the drink will naturally drop.
This design is exquisite and practical, which can be used as a stirring rod to stir coffee and a straw. Kill two birds with one stone, which is very convenient.
