Looks to me like probably none of the flies have ever actually been used but I can't swear to it, but its obvious at least most weren't.  I haven't checked each and every fly.  The box is in great shape, just a few minor scratches/scuffs.  It's about 68 flies give or take.  The box measures APPROX 7 x 3 5/8 x 1 1/2 inches.  Maybe some call this a Wheatley Style Box...not sure about that.  Nice Box.
