This Japanese made fan is produced by applying Kakishibu varnish (derived from tannins from unripened and fermented persimmon) on Japanese paper, spread over the ribs made of bamboo, this traditional temperature regulator is an awesome tool for hot-and-fast charcoal grilling (K-bbq, yakiniku/yakitori etc).
The protecting layers of varnish prevents the burning of the paper from charcoal sparks, and the flexible bamboo ribs have just enough bend to produce maximum airflow when needed.
