From Nanoblock's NanoGauge series, it's the new Series E7 Shinkansen! Looks great displayed on its own, or combine it with NanoGauge rail sets and accessories (sold separately). (Please note that the pictured NanoGauge railway track parts are NOT included and are for reference only!)
Nanoblocks are "micro-sized building block" toys that require assembly. Please note that Nanoblock pieces are very small and tweezers can be helpful (although not required).
