This is an injection plastic Mini 4WD car model.
From the Tamiya website:
This is a premium version of the car driven by hero Yonkuro Hinomaru in the hit Japanese Mini 4WD cartoon "Shin Dash!! Yonkuro". The race-proven Super-II chassis provides a fitting base for the car. Its rear roller stay and gear case are molded in light gun metal ABS. Yellow large-diameter 6-spoke wheels are paired with slick tires. Features newly-designed metallic type stickers. Will measure 150mm long when complete.
Requires two AA size batteries (not included).
