Foil strip CD tweaks...A mystery

I'm sure most inmates are aware of the P.W.B foil that is applied to CD's to improve the sound. There have been fantastic claims of improvement, although, of course, some claim they hear no difference at all. I received some from a friend and I thought I heard a difference of some CD's not others. Then one day, my young son was applying stickers to his notebook, and don't you know it appeared to be the exact same foil, pattern, thickness and all! Then as these strange occurrences would have it, I noticed one of my wife's hair clips had the exact same foil with the exact same pattern, albeit within the clear plastic substrate of the clip so that I couldn't actually touch the foil.

Now is it reasonable to at least postulate that all these apparently identical foils come from the same original source? And if so, who is responsible for their original design. Is this a case of an expensive audiophile tweak posing as a cheap child's sticker, or a cheap child's
sticker posing as an expensive audiophile tweak?
