This is an injection-plastic kit of a science-fiction/anime item.
From the manufacturer:
Shinkalion Mode has been brought to life with a new plastic model of the Shinkalion E3 Tsubasa Iron Wing!
From "Shinkansen Henkei Robo Shinkalion" comes a plastic model of Shinkalion E3 Tsubasa Iron Wing! The mecha has been brought to life while preserving its unique appearance from the show. It features fully articulated joints, allowing you to recreate all kinds of action poses. Use the included Shin Fumikiri Shuriken to recreate Shuriken Mode and Kunai Mode. Combine with MODEROID Shinkalion E3 Tsubasa (sold separately) to recreate the "Double Fumikiri Shuriken!" scene from the show.
The model kit is made of PS and ABS plastic with POM use for some joints, and features runners separated into four colors (three shades of grey, green). The kit also includes pre-painted parts and decals, so all it takes is a simple assembly to recreate the mecha from the series.
*This model is meant for display in Shinkalion mode. The model cannot be transformed into Shinkansen mode.
