(K-String official commercial)
K Strings (Kitty Strings) is a string manufacturer that makes strings specifically for yo-yos. Since the owner, Hirokoba, started making strings in the Philippines in 2007, he has continued to improve his strings while incorporating user feedback, and they are loved by many players from beginners to world-class players. World champions use them when winning world championships, and yo-yo brands have started to use Kitty Strings as the strings that come with their own yo-yos, and they have grown into the string manufacturer with the largest market share in the industry. In 2020, they moved their base to Japan and are now developing new Made In Japan strings.
