LEGO The Lord of the Rings BrickHeadz are based on the The Lord of the Rings franchise and sets. These BrickHeadz sets feature stylized, blocky representations of popular characters such as Gandalf the Grey, Frodo, Gollum and Balrog. They are built using LEGO bricks in a standardized scale and form, with a distinctive squared-off design, large eyes, and a compact, displayable size. BrickHeadz has been particularly popular among adult fans of LEGO (AFOLs) and collectors due to their display-friendly nature, the wide range of characters, and the unique, recognizable style.
