This is a collection of GI Joe accessories for the 1991 figures Big Ben, Low-Light, Red Star, Snow Serpent, and Tracker.  Note that Low-Light's accessories includes a knife that's not really visible from the pictures (the guns obscure its view).  Note the stress mark on one of the side flaps of the Snow Serpent backpack.  It seems to have normal strength regardless of this.  Free USPS Ground Advantage Shipping.
