Definitely work well in my woodgas stove with a lighter, hadn't thought of leaving a bit of cotton wool unwaxed to aid lighting with a firesteel/rod, will try that next time if they don't work so well without the lighter when I try that next few days ie when it stops raining long enough !
Have also cut them in half as I suspect that it may not need a whole one most of the time, but again subject to testing !
