E5 Series Shinkansen Hayabusa N-gauge 10-1663 Basic Set 10-1664 Add-on Set A 10-1665 Add-on Set B Thank you for viewing. I believe it is unused, but it may have been test-run. It was sent to KATO due to a manufacturing error or something and has been kept as is since its return. The outer box has some damage. Please check the photos carefully and purchase with no returns, no claims, and no cancellations. If the item is out of stock, the transaction will be cancelled. Thank you for your understanding. #ModelTrain #Ngauge #Structure #Layout #Diorama #KATO #Kato #TOMIX #Tomix #Tomytec #Geocore #Greenmax
