Core77 just posted this video of somebody who has found out that all you need to do to open a locked and zipped-up suitcase is a simple ballpoint pen. You don’t have to break any locks and in the end, you can simply reseal the zipper and make it look like nobody even went into your suitcase.

It’s times like this when I’m glad that my family has always taught me to tie my suitcases with string (like a present) so that even if this technique was used on my suitcase, it would clearly look tampered with (unless the person also imitated our knot exactly like we had it).
