She does a great review of the kisslocks. And she triggered a memory in me - my nan had something similar she would put her cigarettes in.
Kisslock (or snap) cigarette cases were very popular in the 60s, esp 70s, still popular with some smokers. My mom always carried a small snap change purse - back when we could actually buy anything for less than a dollar.
That easy secure closure just can't be beat.
