A new era of your darting career has dawned when you bring the Viper cobra Soft Tip Darts, designed for use with either electronic dart boards or most sisal dart boards. These darts are packed with features starting with the barrel, fashioned from 90% Tungsten and 10% Nickel. Tungsten is a very dense metal, able to create slimmer darts with the same weight as lighter metals; this allows for tighter shot groupings without sacrificing control, increasing your scores. Tungsten is a sign of quality and durability as well because of its density. A higher tungsten content will produce a slimmer dart profile than one with less. More tungsten in the dart increases the price as tungsten is a rare metal and its density takes more effort to machine. The increased price gives a higher quality barrel and can improve performance, increasing scores. Each barrel enjoys diamond-cut engravings bands, allowing your grip to remain consistent throw after throw. The Cobra Darts feature tough, lightweight Aluminum Shafts, with diamond cut etchings for a fierce look. These shafts feature locking holes that allow a more secure fit to your barrel; you won't find yourself re-tightening these shafts after a shot or two. Finally, each dart is finished off with a slim flight, for a pro style look. Each set includes six high speed slim flights, three extra nylon shafts, nine 2BA Tufflex II Tips, dart mechanic repair tool, and a Deluxe Dart Pal Case. The Deluxe Dart Pal Case is a great all-in-one solution for your new darts. Featuring a hard outer shell and cloth lined slots to keep your dart secure, the Deluxe Dart Pal has room for everything included in this set!
