YYF String (poly100%) x25 Orange Color

YoYoFactory - YYF String (poly100%) x25 Orange ColorThese strings are robust 100% polyester. They are designed to contrast sharply with your surroundings, highlighting the motion of the string. Because they are dyed, they are ever so slightly thicker than an uncolored polyester string. This lends to a slighter stiffer string, just one of the many appeals of colored strings.These strings are not recommended for use with yo-yos with starburst response systems; the friction from the starbust system wears the polyester too quickly. For those yo-yos, we recommend using 50/50 Cotton/Poly mixes.These strings are almost identical to any other company's 100% polyester strings.
