This is an injection-plastic jet aircraft model kit.
From the Hasegawa website:
Two eggs with a side of awesome. Break out the egg timer, these birds assemble fast. Their designs are poached from the F-4 and the F-15, two grade A planes that have served the JASDF practically since it hatched. F-4s have been scrambling since 1958 and they're still a highly effective ground attack aircraft. The F-15, comparatively, is a spring chicken. It's a light and fast air superiority that has been crated and exported to many countries. Kit features two eggplane-version kits with full decals.
Includes parts to build 2 model kits. The F-4 parts come molded in black, and F-15 parts come molded in gray. Includes clear parts and decals.
