The security label is made of polyester film and the protective liner is glass paper.

After we stick it on the surface of the content, there is no difference from ordinary labels. But when we tear it off, the hidden words 'VOID' or 'VOID OPEN' will appear. It completely transfers to the surface we stick it to and cannot be fixed to come back. This means that the content is open.

The hidden message can be customized, we can put any word or graphic in it, like bar code, serial number and more.

The low transfer means that when we tear it off, the surface we hold on to will reveal the words 'VOID' or 'VOID OPEN' and the rest will remain on the sticker.

High transfer means that when we tear it off, the words 'VOID' or 'VOID OPEN' will remain on the label and the rest will be revealed on the surface we are holding onto.

No transfer means that when we tear off if we take it off, both the words 'VOID' or 'VOID OPEN' and the rest will be revealed on the sticker itself.

The sticker image size and design can be customized.
