This item was purchased from a used hobby shop. The box has "sample" written on it in marker from the time of purchase. It is unknown whether it is a sample item. The modification parts inside are unopened. Since they are unopened, I believe there are no missing parts. An instruction manual is also included. Please ask if you have any questions. I will ship via Takkyubin Compact. YAKUT DOGRAM Fang of the Sun Dougram Modification Parts Takeshi Chiba Modelers At Work Plastic Model Sunrise
