From the late 1970s or early 1980s, unopened.  It does not surprise us too much that these are available all over the internet, so we borrowed someone else’s description of the probable (but not guaranteed) contents of the kit they were selling:  “Navy blue. Contains toothbrush and toothpaste, disposable razor, plastic hair comb, shoe horn, flight socks and toiletry sachets. Clipper class was for frequent business flyers.”  Another seller points out that contents of these bags varied quite often.  We are not going to open ours to find out.  Grades: 1
