BrickEconomy Member Review

“This rare 2016 LEGO Ninjago Sky Pirates polybag (set 5004391) is a fantastic addition to any Ninjago collection. The exclusive Siren minifigure with her unique design and alternate face stands out, despite the lack of back printing. The posable robot build and detailed accessories, including ninja weapons and a collectible map, add value.”
