A folding fan is a portable cooling device that has been used for centuries in Japan.

	Fans are typically made of bamboo ribs and paper. A metal pivot is an essential part to keep ribs in place. Paper, on which various pictures or letters are drawn, is pasted over this framework.

It is easy to carry around folded up.
By waving a fan, you can get a quiet and gentle breeze.
Not only as  cooling devices, folding fans are used in innumerable occasions such as rituals and classical Japanese dance. 

Since a folding fan spreads out wide toward the end, people think them to be symbols of good luck.
