We hacked the healing process by turning a medical device into a new way to play. Introducing LEGO Rebuild the Cast. We redesigned the traditional fiberglass cast wrap to feature a flexible, LEGO-compatible texture. Suddenly, a fractured arm isn't an injury, it's the canvas of a buildable experience, because if LEGO has taught us anything, it’s that even when things fall apart, we can always build them back better.
