I ordered tamper resistant labels and although I ordered 10, I actually received 16 which was appreciated. I ordered them on the Sunday evening and they arrived on Thursday via DPD and were exactly the size I needed. This may be my fault for not researching properly, but the tamper resistant is if you peel the label it breaks into smaller pieces so it’s obvious someone has tried to mess with it, but it doesn’t actually damage the surface/paper it was stuck to, so if you sat there long enough peeling it, there would be no proof it had ever been there, and that’s what I needed it for. All in all though, it was quick and easy system and you just need to make sure you accept the art work proof to speed production.
