The cup body of the current application is comprised of 1) a staged cup wall, 2) an open mouth, 3) a bottom wrinkled with concentric circles, 4) a straw guide developed on the wrinkled bottom, 5) an upper snap on cup developed along the perimeter of the open mouth, 6) a lower snap on cup developed along the perimeter of the wrinkled bottom, and 7) a bowl shape lid having a large center hole. The length of the straw guide is longer than the height of the upper cup. The upper end of the straw guide almost reaches to the large center hole of the bowl shape lid. The straw guide is developed on the wrinkled bottom of the cup to allow the straw guide lean aside freely. The center hole on the bowl shape lid is large enough to allow another straw put into the upper cup through the gap between the straw guide and the center hole.
