They start easily with any flame and burn for quite some time. An easy way to get a fire started.
Its really a combination of tinder and kindling. Easy to start with just about any flame.
To me it is a far better choice for emergency fire starting than trying to get something started with a fire steel and home made or found tinder if you are cold and wet.
I did not try shaving bits off of it to try and start it with a fire steel.
Any match or lighter starts it right up.
