K-Cedar is a leading Korean string manufacturer in the field of tennis string innovation and exports to more than 20 countries.


It changed from KUKJE String to K-Cedar in 2017 and as the only company in Korea to produce tennis, badminton, squash, and soft-rocket strings. We started producing products in 1974 in Korea, which is the wasteland of string.


We  are currently producing as O.E.M from a famous foreign brand in recognition of our excellent technology.


If you try K-Cedar's product by yourself, you will feel and believe that it is superior to any other product. However, we are not satisfied with this and will do research and development constantly so that we can always be a good friend to tennis players.
