This is an injection-plastic aircraft model kit.
From the manufacturer:
Designed by engineer Takeo Doi, the Ki-10 was the last fighter biplane used by the Imperial Japanese Army Air Force. It boasted fabric-covered, all-metal construction, along with twin 7.7 mm (0.303 in) Type 89 machine guns which were synchronized to fire through the three-bladed prop. 280 Ki-10-II aircraft in all were built by Kawasaki between June 1937 and December 1938. This limited edition kit features two Kawasaki Ki-10-II Type 95 Fighter kits, along with two marking options.
Includes parts to build two kits. Parts come molded in gray. Includes decals.
