Tetra Pak is widely used all around the world. A kind of Tetra Pak is in the shape of pillow. Almost everyone open it with their teeth and drink without a straw for convenience but it is quite insanitary. To solve this problem, “Clean Kiss” covers a sheet of foil on a cut corner of the packaging. Tear off the foil and you can enjoy a clean kiss with your drink.
