Insights

A magazine gift from 2018, Kai (891842) was broadly distributed and lacks unique parts compared with other Ninjago variants, so scarcity is limited and remake risk is elevated, while the franchise’s enduring fanbase provides baseline liquidity but little upside.

Set Facts

Included in Lego Magazine Ninjago 2018 Issue 10 called Dragon Race!, released on 3rd October 2018.
It was included in Dragon Race!, the 42nd issue of the Ninjago Magazine.
