LEGO 891842 Kai

Released 2018 · 14 pieces · 1 minifigure · Ninjago

LEGO Kai (891842) was released in 2018 as part of the Ninjago theme, with 14 pieces and 1 minifigure. It is one of the smaller Ninjago sets, larger than only 23% of them. It was one of 46 Ninjago sets released that year (see them all). Released in 2018, 8 years ago, well past the two-to-three-year run most LEGO sets get, so it is almost certainly out of production.
