Panel (57 parts)

A selection of smooth elements to give Technic models and nicely finished appearance.

The LEGO Group has created a huge number of Technic 'Panel' Elements in recent years which can give the exterior of the model exactly the right shape. This is especially true in the high-end Technic Supercars which need to match the appearance of a complex curved vehicle.
