Fire Piston Secret “Survival Kit” Cap & Hollow Plunger

This cap converts any of your Clear Plexglass Fire Piston into a more complete ‘survival kit” by allowing you to store survival supplies in its hollowed out compartment.  This is the came cap that comes on the Survival Kit Fire Piston.

Simply unscrew the cap off any of the Plexiglass Fire Pistons and screw on this cap.  The cap comes with  an O-ring sealed screw cap and houses both a hidden fire-steel sparking rod (ferrocerium rod) and solar burning lens with room to store tinder, cotton ball or other necessities.
