I really want to find these nail foils......

Or I think that is what they call them. I am trying to make a mirror looking look on my nails, but I am wanting to buy it from either a store or a known company. But after much searching, I haven't found any at all. Does anyone know what I am talking about and where I could find something like this. The only place I could find was on Ebay. If you don't know what I am talking about please don't respond with I don't know what you're talking about. Only people who have an idea of what I am talking about or who would know what other ideas I could do to get the mirror look on my nails. Thanks.
