I got a Coghlan orange match safe similar to the one you bought with the small ferrocerium rod. I managed easily to ignite a cotton ball by using the teeth of a hacksaw blade. I had to place it really close to the cotton ball and give a quick strike.

BTW according to my experience these orange match safes from Coghlan are not watertight unless you change the mediocre O-ring. Put a match in it and submerge it in a glass of water for 30 min and you'll see if your match is dry or not.
