There are a few different replacements for a triple flint lighter. One option is to simply replace the flints in the lighter. This is the least expensive option, and it is relatively easy to do. To replace the flints, simply remove the screw on the bottom of the lighter and take out the old flints. Replace them with new flints and screw the bottom of the lighter back on.

Another option is to purchase a new lighter insert. This is a more expensive option, but it is also more durable and long-lasting. To replace the lighter insert, simply remove the old insert from the lighter and insert the new one.
