The Evolution of the PROMISE Lighter Design

The PROMISE lighter design has not been a subject of significant evolution. This is because PROMISE does not refer to a specific lighter brand or design.

It's possible you are thinking of a different term or have a misunderstanding.

Could you please clarify what you meant by "PROMISE lighter"?

Perhaps you are referring to:

* A specific brand of lighter: If you know the brand name, please share it.

* A specific type of lighter: For example, a Zippo lighter or a disposable lighter.

* A particular design feature: For example, a lighter with a unique shape or a specific ignition mechanism.

Once you provide more information, I can better assist you in understanding the evolution of the lighter design you are interested in.
