The Ti Survival Exo Runt Titanium Lighter is small enough to put on a key chain for everyday carry or tuck away in a pocket or backpack. The titanium lighter is fitted with an o-ring, so the fuel inside will not evaporate. This is a huge advantage over unsealed flint lighters, which may lose their fuel to evaporation in a few days, even if unused. This Exo Runt has a stonewash finish.
