Takara Tomy Plarail Doctor Yellow S-12 #TakaraTomy #TakaraTomyPlarailDoctorYellowS-12 It has been opened, but it's unused. I think this is more for collectors than for children's toys. I am not an expert in selling used items, so please understand that I may have overlooked some details. It was working at the end of last year, but I haven't checked it since then.
