PACK OF 9 FLINTS
The Dunhill Blue flints are slightly slimmer than the red flints more in line with standard lighter flints and are specifically designed to work with your Dunhill Unique lighter. It is also a requirement of the guarantee that you use them and for once they do make a difference (and not just to your pocket)
Dunhill flints are slightly softer than the cheaper competitive products and therefore, using a Dunhill flint will create a greater spark and will reduce the wear on the flint wheel. This will extend the time between services.
