An apparatus is provided that includes a mold that includes a first cavity defining a toothbrush body, a first injection unit in fluid communication with the first cavity, and a second injection unit also in fluid communication with the first cavity. An apparatus is also provided that includes a mold that includes a first cavity defining a toothbrush body, a second cavity defining a toothbrush body, where the first cavity and the second cavity define substantially identical toothbrush bodies, a first injection unit in fluid communication with the first cavity and a second injection unit in fluid communication with the second cavity.
