Luggage Bag zipper safety

We have seen a lot of YouTube video show that how easily to open a zipper on a bag by using a ball pen. I have tried it as it is that easy with just a poke in between the zip and it is opened. Many of friends who travel a lot are worry not that people will steal item from their bag but people putting something that not suppose to be in.

And so most of them uses a hard case luggage bag with a clip on number combination lock like a briefcase, well lets call it giant briefcase OR they will wrap their bag in plastic at the airport. I am not keen with both solution mainly I am worry if the combination lock spoil which pretty often then I probably have to smash the bag into pieces and wrapping is just not my thing.

So, I though of how to improved the security using zipper bag. I am not sure if this is a foolproof but is worth to try. After you done with packing, zip up your bag and zip your bag all the way to the end don't 1/4 or in the middle since now all bag come with 2 zippers. Then and if possible when you check in or scan the bag, have the security guy or ladies at the counter to stick the security sticker just beside the zipper. This way, if the crook open the zip with a ball pen and he would have to move the zipper to close it back and this way he definitely would destroy the security sticker. :) In addition you could also get luggage strap with combination lock as an extra security  :)

I use a tape as a sample security sticker :)
