Perhaps, but some "known brands" like Vapcell just re-wrap something else (and they can change the underlying cell at any time, without you knowing where it actually came from). For example, the Vapcell G50 I purchased a year ago is actually ... a Sumsung SDI 50G. Whether that still holds today is unknown. Some people have had more recessed terminals, which would hint at Samsung 50E.
Why do they do this? Because many high quality manufacturers (Samsung, LG) don't approve their cells for usage in vaping devices. Some like Molicel are OK with it. I'm sure you have heard of Mooch :)
Although, I do have a pair of these in front of me right now, bought a few years ago, and I can't find any mention of Samsung, or any other manufacturer, on them.
I've found another vape shop advertising those [0]. I would have expected consumer protection to crack down on them for false advertising, since this is in France and these shops have been operating for at least two years. They also have physical locations, so it's not like they're some kind of "dark store" that moves every week...
