The new PRESTO Spark Woven Carbon Fiber bow has all the qualities that players love about PRESTO bows: Laser-straight tracking, great control, and outstanding durability. PRESTO spark takes these qualities three steps forward with their incredible finish -- beautiful carbon cloth weave with sparkles of color, in your choice of Blue, Red, Gold, or Silver! Exuberant silver spiral winding fits the look perfectly. And the violin bows even have a silver treble clef inlayed into the ebony frog. (Viola and cello bows have Parisian eye).
