LEGO Mini Tightness typically refers to how snugly LEGO minifigure parts or small bricks fit together—especially the joints like arms, legs, hands, or accessories. A good level of tightness ensures durability and poseability, while parts that are too loose may fall off easily, and overly tight pieces might be hard to move or at risk of damage. Collectors and builders often use the term to assess the quality of minifigures, especially when buying pre-owned or rare items.
