security labels that leave permanent residue

Yesterday I was down in London and whilst travelling on the underground I took these 2 pictures of the residue left by security seals used to seal cabinets and fire hydrant areas.

at least 5 different seals have been tried here and left residue

Nice.

If you have an issue like this in your workplace, then take a look at our no residue Label Lock product range or watch the YouTube security labels video of them in action.
