BrickEconomy Member Review
“The LEGO Sonic the Hedgehog Knuckles and Shadow BrickHeadz set (40672) features detailed and accurate mini builds of Knuckles and Shadow. The set is praised for its sturdy construction and the use of unique pieces. It's highly recommended for Sonic fans due to its nostalgic value and collectible appeal.”
BrickEconomy Expert Review
“This two-character BrickHeadz pack delivers strong representations of Shadow and Knuckles, each using distinct shaping and color work to match their designs from the Sonic franchise. Both models incorporate layered brick-built details especially Knuckles’ head shaping and Shadow’s torso, that add accuracy without relying too heavily on printed elements. Although the eye prints are inconsistent in color, the overall builds pair well with previous Sonic BrickHeadz and offer solid value at the standard two-pack price.”
