Young jeezy beez like download audiomack song. I've been trying to research a way to verify the serial number but haven't had any luck. Dupont fuel is measured to specific lighters.

A few of my ST Duponts, and one vintage Dunhill Rollagas, thrown in for good measure. Please excuse the crappy focusing & generally bad video quality.

All my lighters are genuine items. There are many fakes around. The ST Dupont models are copied widely, especially the Ligne 2. Some fakes are very convincing and need close scrutiny, but there are easy to spot signs to look out for.

Fake serial numbers: one widely-used is 4FK12J8. Anything with ' 4FK ' in the serial is fake. This isn't the only number/letter combination used; most fake serials are machine-stamped with perfectly-aligned letters/numbers rather than the irregular, unique hand-stamp on each genuine ST Dupont. Any limited edition ST Dupont will have a serial stating that item's number in the run, e.g. 1006 / 2500 and if you see an ordinary stamp on any limited edition item, it's a fake. If it says ' laque de chine ' it stands to reason the item should have some Chinese lacquer on it and not be plain gold or silver. If you do a search for Dupont replica sites, many examples of fakes can be found.

Some imitate limited edition items, others don't resemble any Dupont ever made. Any fake sent to ST Dupont for service is confiscated.

Very good site for reference is Dupontcollector.com.
