I didn't realize that I would be received a set of four straws. I thought I would receive only one. Each straw comes with a silicone straw, a straw cleaner, and an easy to carry oval shaped storage unit for each one. You can use the straw on the go, and store it away for cleaning when you get home. It can't get easier or more convenient than this. I love this set and will share with my friends when I am able to see them again. This pandemic is epic.
