DNA YoYo String Designed to free players from dreaded string tension! DNA string is made of high-performance polyester string attached to a swivel system to keep tension at its best during play. DNA your heart out and go Godspeed without needing to adjust your tension. DNA string is a consumable part like regular yo-yo string, and the mechanism is designed to only last as long as a normal yoyo string. We do not recommend attempting to change the string and recommend discontinuation of use when the string is looking tired, just the same as we do with regular strings. DNA String: Short 33 inch Long 44 inch Note string length variance is typically within .5 of an inch. String will stretch with use.
