In an embodiment, an applicator includes an external sheath and an internal rod extending through and beyond a first end of the external sheath. A first end of the internal rod may be coupled to a plurality of axial members that extend between the first end of the internal rod and the first end of the external sheath. By actuating a knob coupled to the internal rod, the distance between the first end of the internal rod and the first end of the external sheath may be adjusted. By adjusting the distance, the configuration of the axial members may be adjusted and this adjustment may modify the amount of product that may be stored between the axial members.
