Review (5/5): Works great with holding vaseline
I make my own kindling strips from 3/16" cotton cord and petroleum jelly (cut to length, simply melt the petroleum jelly over low heat, soak the cord, take it out and let it congeal)...and these little jars are not affected by petroleum jelly at all...so they stay like-new for years, while containing the petroleum jelly-soaked cotton cord.
