I keep looking at the zip tie picture. The white rectangle in the middle of the stop pad looks at first like the head of a cable tie. But there's the same feature on the stop pad above also; it seems to be a pixelated image of the adjuster screw on the pad.
With that rectangle covered up, what's left doesn't look unlike a zip tie, but to me the uncanny resemblance is gone. And if an adjuster screw can look like a cable tie head, perhaps something else could look like the rest of the tie. I'm just wondering how sure we are it really is a zip tie.
