Some of the security measures for your suitcase might not be quite as safe as you might think.
An airport security guard has shared a clip that shows just how easy it is to break into a bag with a combination lock - using just a pen.
The guard, who works for the Transport Security Administration in the US, appeared in a viral clip on TikTok account @geenaanac.
As reported by The Mirror, he said: "If you're ever travelling, make sure you are aware of how security systems in your bag can be breached.
"A lot of people I see travel with locks on their suitcases with special combinations, but with just a pen, you are actually able to breach a suitcase's security.
"The pen to the zipper technique has been around for tons of years, so I wanted to show you guys this, so you know to look out for it.
"I'm just going to go all the way around and this once zipped up bag was opened with just a pen."
Suggestion for a more secure kind of bag, the security guard said: "The best kinds of zippers have covers over them. That's an extra added layer of security for your luggage when you're travelling."
The clip received 9.3 million views and just shy of 390,000 likes, with social media users taking to the comments to share their thoughts.
One person said: "Always clingwrap your bags. Most airports have this as a service, but you can do it at home," and another added: "Just don't store anything valuable in luggage."
