I purchased this at the Shinjuku store a few years ago. The total cost was about 40,000 yen. The main body is noticeably dirty, but I think it can be cleaned up with baking soda, etc. The amount of oil used is as shown in the photos. The set includes the following: Brass oil burner Oil burner blend, all 4 types + 1 type - Joséphine - Simone - Catherine - Béatrice - SHIRO White Lily (used a few drops)
