Sorry for the ambiguity, its hard to be more detailed without giving it away.
The product is well known, but comes in many different brand names & manufactures, all slightly different. There is one manufacturer that sells a lot of their own branded product on eBay. But they also sell it wholesale unbranded, allowing you to put your own label on it. So their not a fake, their not trying to mimic another brand.
Does that help?
There is a lady who has done this & set up a nice little business, which is what gave me the idea plus I also use the product myself. It's based in Vic, I'm in qld. She is selling the product as her own brand. So I'm yet to determine if there is adequate market for it up here, as I would be a competitor.
