This is a Micro Ace 455 series Akabe-e livery 3-car set. Operation is not a problem. "Junk Points" * Micro Ace genuine white interior lights installed (lights up) * Micro Ace genuine couplers replaced * Some parts of the M car's ceiling glued (I reattached the parts that were broken when I bought it, see the yellow circle in the 9th photo) * The diaphragms of the connecting sections are partially different (I took the parts from the same Micro Ace 455 series, but they may have been different to begin with) There may be other oversights. Thank you for your understanding. Thank you for looking.
