nanogauge Basic Full Set E5 Series Shinkansen Hayabusa Nanoblock version N gauge Basic Set Hayabusa - Operation confirmed The ruler-like part is missing. ↓ It was there! The main body and rails are all present. Instruction manual included. All spare blocks are also included. I don't think there are any other missing parts, but please understand that there may be unintentional oversights. I bought it new and only played with it once, so it's generally clean. The outer box has tears and stains. Please understand that this is a used item that has been stored at home for a long time and has been used by a child. Please check the images and description carefully before considering a purchase.
