Straws often appear when ordering coffee or other drinks.
But there is something to be noted about the folding of some straws.
1. Do not use straws for hot coffee or hot drinks. There is a great chance that your mouth will be burned.
2. The second folding method in the picture can easily lead to liquid reflux (at present, there are still many places to use this, it is recommended to change it, dripping on the customer or on the table is not a good thing.)
3. There are many "three nots" straws, which may be made of waste plastics and will produce toxic substances at high temperature. When buying straws, you should choose those with QS certification.
