Maybe a lot of people have such habit. Going out in the morning to buy a box of milk from the supermarket.The straw mouth on the box surface.It often drops ash.It is dirty.Then the straw suddenly disappeared when the time you drink. It makes you can not drink.Everyone must be so annoyed.So we do this improvement: still is our habit of carton packaging.But when you put the box top open, you will find that have to change the location. It is hidden in the box inside and the straw was also caught in the side.You no longer have to worry the straw disappears.This is a new way of drinking.It also makes the milk box become more clean and health.
