This great brand originated from a Kid who was obsessed with machinery. Compared with the finished products, he prefers the process of splicing and assembling.
To challenge more difficult projects, he made full use of his leisure time to acquire the essential knowledge. After graduation, an idea came to him: why not make this hobby for a living? And it worked. He started helping his neighbors repair cars at the garage. During the time, he noticed that many expensive parts should be at a low-cost level and easy to be produced, so it‘s worth having a try about the DIY motor parts. That's the start of "KOJEM". With the growth of his career, he had not only acquired more professional knowledge but also access to high-quality and low-cost suppliers around the world. Until now, his KOJEM has helped millions of car enthusiasts experience the joy and fulfillment of assembly at a lower price under the belief of "keen on joy, explore machinery".
