- To attach any of the modular storage tubes, you must first unscrew the magnetic mount end cap from the Fotialamp flashlight. Afterwards you can simply screw the desired tube length in place and close it off with either the magnetic mount end cap or the regular end cap included in the survival kit.
- You can assemble the storage tubes in different configurations: Long Tube + Fotialamp, Short Tube + Fotialamp, Long Tube + Short Tube + Fotialamp, and Short Tube + Long Tube + Fotialamp. You can also cap both ends of the storage tube for carrying it by itself.
