Kiribi lighter flints are soft and are made to be the best quality option on the market. Fitting to the Kiribi style of unique presentation, even their flints are offered in a manner different from the usual plastic pack or finicky rotating dispenser - a tiny glass bottle with a cork stopper.
Pipe Nook Notes
These flints will also work with other brand lighters that take replaceable flints, such as the Peterson pipe lighters.
