Machined from billet aluminium coupled with a centre spoke section integrated with a pencil sharpener under the centre hole. The waste can be disposed of esaily through a flip cover in the base. The design of the wheel follows closely that of a real Formula 1 wheel.
這個方程式賽車輪圈削鉛筆刀是以鋁坯經機械加工切割後，再結合中間附有削鉛筆刀的中央輪幅。只要翻開底下的蓋子，很容易就能處理削下來的鉛筆碎削。它的整個造型和真的一級方程式賽車輪圈十分接近。
Diameter: 4.45
