A housing has upper, lower, and central sections having a common axis and forming an interior chamber. An opening in the intermediate section has upper, lower, and sides edges. A flap has one edge coupled with the opening and covers the opening. A support is slidable between extended and retracted orientations. The support has central, upper, and lower extents. A cylindrical bore extends through the support. The support has legs, including a short leg, extending downwardly and outwardly and adapted to be radially contracted with the short leg within the opening restrained from downward movement. The flap is adapted to be depressed to move the short leg from contact with the opening and spring the legs outwardly to move the support from the extended orientation to the retracted orientation. Upper and lower needles extend from the upper and lower extents of the support for movement therewith.
