I bought this to use for "Young Frankenstein the Musical" for the Hermit scene. Works great and has
been flawless for 19 performances.
It is basically a Thumb tip with a rope wick with a metal
thump protector and some cotton. It uses Lighter fluid for the fuel.
One tip they don't mention.
When the wick gets a little short the flame gets smaller. The fix is to pull more wick out of the
thumb. The wick runs the length of the thumb and the cotton feeds the wick. Pulling the wick out a
little and you get more wick to flame up. I adjust it every 6 or 7 performances and this works
great.
