Price reduced to 4750 yen, 5% off, until November 30th! This is an authentic LEGO product. The box and spare parts are not included. The items are all as shown in the photos. Some minifigures have loose arms. I disassembled and reassembled it once, so I don't think there are any missing parts, but there might be oversights. Please understand this before purchasing. *It may be partially disassembled for packaging. Thank you for your understanding.
