Radar Report

Our view on this set, in plain English.

Collector Confidence 93%BUY & HOLD

Modular series premium builds over time

Modular buildings are the closest thing LEGO investing has to blue-chip equity. One release a year, an intensely completionist collector base, and a near-perfect record of post-retirement appreciation.
