Price includes 100 green strings. This string is 100 percent polyester, instead of cotton or blended like most yoyo string. Polyester insures less friction and more durability. We recommend these for advanced level yoyos and those who practice a majority of complicated sleep tricks.
It is Type 6 string, which means it is the same width as Slick 6. If you are new to yoyoing, you should know that strings can wear out pretty quickly! Fixed wooden axles can wear out string the fastest, because you get the most friction. When your string gets dirty or starts to look worn, it's better to throw it away and put on a new string than risk a string break that can send your yoyo flying.
