Same goes for anything "locked" with a zipper that still moves. One can open the zipper with a pen, go through your belongings without you knowing, then close it back up with the zipper. Atleast buy a case with zippers that lock into place.
Yesterday I had to open a couple of cabinets at work after the keys went missing. I only watched a few YouTube videos and I figured how to open them with my Swiss army knife.
The first one took over an hour. The rest of them took a few seconds. I was amazed how easy it was.
Yes, it was a chest freezer with one of those little filing cabinet locks. It genuinely never occurred to mum that her eight year old could pick it with her hairpin.
