It is commonly seen in "Frozen style (sherbet like cocktail)". It seems that there seems to be someone who seems to be thinking that this will come "to drink one cocktail for two people", but it seems to be different in reality.
This straw is a straw for stirring a cocktail, which is called "steering straw", mainly frozen, and it becomes watery and easy to separate when ice melts.
Originally it is "straw for stirring", but it seems that you can use it to drink it. In that case, because it is a thin straw, it seems that it is stabbing two in the sense of spare because it is easy to clog ice if it is one. For that reason, we will use two at the same time.
Even so, since "steering straw" is very thin, we need power to inhale and it seems that there are many things that does not look smart in many cases. It seems to be better to use it for steering (stirring) when an extremely thin straw comes in, or when only one is used.
Another straw that comes with "crushed ice cocktail" which crushed ice finely is called "drinking straw." In the case of "crushed ice cocktail", I will use this straw because fine ice will get in the way when trying to drink with a cut in the glass.
