I am a smoker. I don't smoke at home, but if you are sensitive to the smell of cigarettes or are concerned about odors, please refrain from purchasing. I am concerned about causing inconvenience or trouble. I do not have any pets. This is a set of 6 DVDs of the challenge from Yukito Ayatsuji and Arisugawa Arisu, "Armchair Detective" ① to ⑥. I am not selling them individually. I have been collecting them little by little for about 20 years because I love mysteries. All items are used. I have watched all of them 2-3 times each. In my subjective opinion, ① to ⑥ are relatively clean. There is a small dot-like scratch on ④, but I don't think there are any other noticeable scratches. The cover of ④, or rather the paper, is creased. I have confirmed that they work. I am not considering price negotiations. I will consider it at a later date. Sorry. ✩ Instant purchase is OK. For those who understand that these are used items, thank you. Due to work, I may be late in responding or shipping, but I will handle everything with sincerity. Thank you.
