This Formula wheel egg cup is CNC machined from solid aluminium billet and them coupled with a plastic centre spoke section. The front inner rim follows the contour of an egg to hold it in place like any other egg cup and the shape of the out rim makes holding it easy.

這個方程式賽車輪圈造型蛋杯，是用整塊鋁坯以電腦銑床直接加工出外框，再加上塑膠製成的中央輪幅組件而成。輪框上方內側的形狀，設計成剛好符合雞蛋的橢圓形輪廓，外側就像一個握把，取用十分方便。
