You will inevitably need replacement string for your yo-yo at some point. And we actually recommend that you replace the string regularly in order to keep the correct frictional properties of the string, which can be lessened when it starts to wear and fray.
We stock both cotton and polyester strings. These are the industry standard materials for yo-yo strings. With great brands such as Henrys and Duncan, you’ll never be out of good quality string to help you master those fast spinning tricks.
