Insights

A magazine promotional piece tied to Ninjago, Kai (2017) sees steady baseline interest from series collectors but wide initial distribution and common parts have left sealed examples plentiful, and the non-unique Kai minifigure plus frequent reissues keeps long-term upside limited.

Set Facts

Included in Lego Magazine Ninjago 2017 Issue 9 called Boom!, released on 27th September 2017.
Kai was designed by LEGO designer Nick Vas.
