Here's my full collection of Ligne 2 lighters from AliExpress.
As far as I can tell all of the deeply engraved Ligne 2 lighters are properly constructed of pure copper, they're certainly heavy enough for it.
The "Chief" on the top left there is an unusual wick lighter and not butane, but it appears to be copper and the fit and finish is top notch.
I should note that the Kuboy lighters (which cost much less) are made of Tin more than Copper, so I can't speak to their longevity, but at least they function just fine to start with.
And the soot to prove two of them are in active service.
