This is premium Type 6 100% Polyester yo-yo string Ultra bright!
Works with all Yo-Yos.
Yo-yo string should be changed periodically. Manufacturers generally recommend changing the string after about 30 minutes of play time, or if the string becomes dirty or frayed. Non-bearing yo-yos will wear out the string quicker.
Don't trust your yo-yos with just any string. Zeekio has been providing quality yo-yo accessories, including premium quality strings, for almost 10 years. Go with a trusted name, Zeekio!
