To solve the problem which straws are easily drop in to the aluminum beverage package , so we create this new product.
There is a special point about this new straw:
When you put the straw into the beverage package ,the facility on the straw will become a three-dimensional ball and that ball is the equipment to prevent the straw to drop into the beverage.
