The KO brothers began practicing pool regularly around the age of 12, with their father Ko Zhi Ming as their first coach. Their natural talent in billiards quickly made them stand out in the field. After becoming world champions, they decided to develop more suitable and professional billiard equipment for themselves. With 20 years of experience as professional players, the Ko brothers meticulously designed and improved all their products, including tips, jump cues, and chalk. Their products reached a high level of quality and professionalism. They guarantee that the authentic KO products sold on the market are exactly the same as those they use in competitions.
