a flexible main body that is flat and adjustable to an expanded condition to provide an interior cavity sized to receive a silicone implant, the flexible main body comprising an intermediate section, a first tapered section adjacent to the intermediate section and offset from a central lateral axis of the intermediate section, and a second tapered section adjacent to the intermediate section and offset from the central lateral axis of the intermediate section opposite from the first tapered section so that at least one of the first and second tapered sections is separable from a portion of the intermediate section for expansion to a tapered implant guide sleeve, wherein the first tapered section extends away from the intermediate section to a first end that extends parallel to the central lateral axis, and the second tapered section extends away from the intermediate section to a second end that extends parallel to the central lateral axis and the first end; and

first and second exterior handles attached to opposing major surfaces of the flexible main body at a location proximate to a first cut line formed on the flexible main body to provide grasping locations when expanding at least one of said first and second tapered sections into said tapered implant guide sleeve.
