It is a sensitive but very imposing and cool fire prop. Since we destroyed so many of then attempting to make this prop we finally have the knowledge of how to make it durable.
I recommend it to theaters, acrobats and dancers.
Although it is the best umbrella I've found it needs careful handling and storage and transport.
Always keep it open when you light up the umbrella, and don't close when the fire is on.
Use lamp oil or white gas. Lamp oil burns at a much lower temperature.
Always shake out excess fuel before you light up.
Have adequate safety personnel and procedures in place before lighting.
