Have you ever gone home with the anti-theft device still attached to your clothes after the checkout process? ? Annoying… You don’t want to go back to the store to have it removed. Several options exist.
Removing a garment lock
Option 1: like an old hard drive
Use a strong magnet, like a hard drive magnet for example.
Option 2: the like bought on Amazon for 15 euros
Use a powerful neodymium magnet, available on Amazon
Option 3: the saw
Sawing around the lock (plastic side), ideally with a mini hacksaw, the small balls inside will eject easily, and unstuck the tip.
To avoid damaging the fabric
Pull on the lock, saw directly the tip, try to cut the tip with pliers.
