These miniature padlock TSA-approved locks are quite COLORFUL as well as FUNCTIONAL.Now, it's fairlly clear that any medium-sized bolt cutter (or maybe even a good set of needle nose pliers twisting the shackle a bit) could easily enough BREAK these locks and effectively OPEN whatever they're sealing up or locking out...But that's not the point. These are the kind of locks we'd say, designed to keep honest folks honest and do the basic first job of blocking open access. And as that, they do a very good job, indeed.They're quite sturdy, and easy enough to set to a different combination than their default 0000 they come with. You just open it up, rotate the shackle 90 degrees, press it DOWN, and reset your new code there, and release the shackle... PRESTO! new lock code.I really like that they're so COLORFUL and they FEEL GOOD on the hand.They're also priced reasonably. Secure FOUR suitcases or backpacks or devices for a single price. And do so with a bit of panache, flair, color!Cool Set!
