lovely solves the difficulty to open the existing milk pack. When trying to open a milk pack, we often experience inconvenience that the entrance is ripped or crumpled without being open. With a tag attached to the entrance, you can easily open it and take it off when drinking milk. Also when the milk pack is displayed, its waterdrop shape can attract purchasers' eyes. When it is open to drink milk, the waterdrop is spread as a heart shape that expresses heart contained in love.
