An ornamental string includes ornamental elements and connection elements connecting the ornamental elements in series. Each ornamental element is formed of two symmetrical hollow half shells sealed together by means of ultrasonic sealing technique. Each half shell has two opposing arched notches such that when the two symmetrical half shells of one ornamental element are sealed together, the two arched notches of the two symmetrical half shells at one side form a hole. Each connection element has a rounded head at each of two distal ends thereof respectively pivotally coupled to one hole on one respective ornamental element.
