Asahi Keikinzoku Zero Katsu Ryoku Nabe 3-liter model. This is the smallest size of the Zero Katsu Ryoku Nabe. I purchased this in January of this year. According to the previous seller, they purchased it two years ago and used it 2-3 times a month. I apologize, but the weight is not included. This is a listing for the Zero Katsu Ryoku Nabe body only. I just washed the pot with dish soap and a new net sponge and let it air dry. Although I washed it, there are a few spots where water marks remain that don't show up in the photos and won't come off. I don't think there is any odor, but please refrain from purchasing if you are sensitive to used items. As shown in photos 8 and 9, the rubber packing has scratches all over. Thank you for your understanding. I will ship via Kuroneko Yamato (Yamato Transport).
