The Unicorn S700 Steel Dart Set is a customizable collection that lets you choose between aluminum or polypro shafts for just the right feel you need for better control. Other than these assorted shafts, this set also comes with a hard carrying case, polyester flights, flight protectors, and heavy-duty barrels. The 21-gram tungsten barrels are super dense and very slim so you can group your darts closer together than you ever thought possible. About Unicorn Frank Lowy revolutionized the creation and distribution of darts when he made the first Silver Comet in 1937. Where previously players got lucky if they got a set of darts of equal weight, Silver Comets came in matched packs of three, precision-engineered for consistency. In 1949, Unicorn became the first manufacturer to sell darts classified by actual weight, and are still the only company that guarantees weight accuracy to .33% on tungsten darts. Innovation didn"t stop in your dad"s day though; today Unicorn is on the cutting edge of dart technology, creating new designs, new materials, and sponsoring some of the top plays in the world. * Durable shafts with 80% Tungsten barrels * Superior grip and handling * Each dart weighs 21 grams * Slim barrels for incredibly close grouping * Complete dart set comes in a hard case
