Your Kiribi Lighter will eventually need new flints. Avoid the guesswork of figuring out which brand will work for yours and buy the right ones -- the Kiribi ones. The simple glass bottle is just about the most attractive way to present such a utilitarian item.

I purchased the Kiribi Kabuto lighter and I could not get it to light so I tried a new Kiribi Flint and still would not light. I thought it was just a junk lighter so threw it in the drawer and bought a Zippo with flints, figured I would try a Zippo flint in the Kiribi and now it works great every strike. The Zippo flint throws double the spark to the Kiribi.
These are the best flints I've encountered. Easy to install in the Kiribi lighters. Long-lasting, lights easily with one stroke. Cheap by comparison for the price. Highly recommend.
In doing my research on the Kiribi lighters I found out that the steel of the striker wheel is a different composition from zippos and other lighters and therefore they do best with Kiribi flints. These are low priced enough that it made sense to buy some when I bought my Kenshi.
These are bar none the best flints I have ever used.
These worked very well with my Pearl Lighter from Japan.
These flints last longer than most. Heavy user.
These Flints fit many Lighters that Robson, Zippy etc are too wide for. Looked high&low to find these on Internet. One fourth cost of Colibri
