If you can establish with a large enough amount of people that you will charge $800 for each zip tie such that when they buy one and wear it, everyone around them can surmise that they must have bought and can therefore afford, an $800 zip tie then I'm sure they'll be happy to fork over the dough to you. If you just turn up, in your utter oscurity with your 500 pack, where buying one from you signifies only that they bought a zip tie and nothing else, they'll just release the hounds.
I thought you were taking the piss but no the safety pin bracelet is real. It is not even made out of silver or gold but cheaper brass. I used to make this type of thing as a kid.
Does it work like a standard zip tie? Is it single use only or can it be loosened to remove and reuse. Have I wasted all my money if I over tighten it and never get an opportunity to wear it.
