I think it's the regular sized esbit. It even says "Esbit" on it. Here, I'll take a pic-



The two white tabs on the left came with the stove, the 2 strips of 3 came in the red box labeled $1.50. The box fits in the folded stove. I made a little X out of steel, I've heard that you get better results that way.

Now that you mention it, it looks like the plastic is yellow, and maybe not the tabs. It's only $1.50, I should give it a try.
