• and
• a collapsible section defined between the proximal end and distal end of the main body,
• wherein the collapsible section is configured to collapse in an axial direction into an ejecting position when an ejecting force is applied to one or both of the proximal end or the distal end of the main body, the main body further defining an ejecting length in the ejecting position, wherein the ejecting length is less than the use length, and wherein the collapsible portion is further configured to return to the use position when no ejecting force is applied to the main body,
