Very interesting. It does seem like the flints have swelled in size, indicating oxidation.

Alberta has a fairly dry climate (low humidity) and maybe that's why these Bics have lasted this long.

For long-term storage, I guess they should be left in the original package or sealed in doubled bags with some silica gel.

As for saltwater, sounds like it could kill my EDC firemakers in hours. Yikes.

Any thoughts on ways to "innoculate" the flint of a new Bic against corrosion?
