Dai Parco People 5: Okatai Rock Opera "Rainy Courtroom, Women are Barefoot..." This is a stage play featuring Takako Matsu, Sadao Abe, Takashi Fujii, Yoshiyoshi Arakawa, Kankuro Kudo, and others. During the play, the audience participates by waving penlights. I only used it once when I went to see the play, so there are no noticeable stains or anything. The light has 8 colors. The color changes when you press the button. Please refrain from purchasing if you are concerned about minor details. You will use it quite a bit during the play, so I think you'll enjoy it more if you have one. It's an interesting play, so please bring it with you when you go to see it. *The items to be sent are the penlight and the instruction manual.*
