Also known as "speed string" this string is a poly / cotton blend that insures less friction and more durability. Recommended for high performance yoyos and those who practice a majority of complicated sleep tricks. Price includes 25 strings.
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.
