Recently added to my collection is a professional dancing sensu (fan), and a new formal obi. I swear, the shipping on these items alone is more expensive than the items themselves.
The sensu in particular is of interest and rather novel. These fans are not to be confused with halloween props, or other such novelties. Rather these fans are professional hallmarks within the dance community. Ones choice in fan, says as much about them as their kimono. These fans are rather stiff, and make a snappping sound when flicked open. You can read more about these fans, and the different kinds used in dance and theater at: http://www.kyosendo.co.jp/english/shurui_frm-e.html
Below is my new fan, and obi. the obis style and theme is that of waves.
