Vintage K&N Air Filter Sealing Grease Tube - Partial -- This is a partial(?) full tube of K&N Air Filter Sealing Grease.  The tube feels like it's only a partial tube full, but I don't know how much came in the original tube, so it could actually be a full tube.  There are no cracks in the plastic and the grease is still pliable.  The tube measures approximately 5 1/2" long x 1"wide.
