A waterproof case that keeps matches dry and the striker with them.

Waterproof matches still need a dry striker, and the cardboard strip on the box is the part that fails first. A proper case solves both — sealed against water, with a striker built into the base that does not degrade.

Most have a compass in the cap. Treat that as a bonus rather than a navigation tool.

This is a buy-once item. It will outlast the vehicle.
