Kitty String - 10 Pack of Fat Kitty String
Kitty string uses a very soft form of polyester that gives you a smoother feel during play and doesn't rough up your hands as much either. They also give you just slightly more length averaging around 43 to 45 inches so you have some extra room to adjust (110-115cm).
(Note: No finger loop is tied in the string allowing you to adjust to your height and tie your own.)
Professionals around the world are beginning to choose Kitty String as their weapon of choice in competition and for good reason. For yo-yo string it doesn't get much better then this.
Available here is the Fat Kitty String. This version is excellent for beginner to intermediate players working on perfecting the bind return. It is also a great choice for people who want to guarantee a nice tight bind so that your next throw is as powerful as possible even with a wide unresponsive gap or konkave (string-centering) bearing.
