Supermarket goods are labeled with anti-theft labels, also called anti-theft buckles, which are used as anti-theft products. Usually posted on underwear, shoes and other items that are easy to be stolen, if the anti-theft tag does not degauss through the security door, it will call the police.

There are two kinds: soft and hard.

Softness is about the same size as the logo of clothes.

Hard buttons can only be used if they are pierced.
