Using this fire - starter set is easy. First, take out one of the waterproof helix tinders. Then, use one of the three fire steels to strike it and create sparks to ignite the tinder. Once the tinder is lit, you can use it to start your fire. When using the set, make sure to handle the fire steels carefully to avoid injury. Store the set in a dry place to keep the tinders waterproof. If the tinders get wet, you may need to replace them. Also, don't expose the set to extreme temperatures for a long time, as it might affect the performance of the fire steels and tinders.
