Take your game from casual to pro with the Viper V-Factor 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 deep shark fin grooves or knurled bands allowing your grip to remain consistent throw after throw. The V-Factor Darts feature tough 150 micron flights. The extra hardiness these flights feature means that you won’t need to replace them as often – they’ll stand up to the toughest throws. Finally each dart is precision machined for maximum aerodynamics and a sleek smooth look. Each set includes six high speed slim flights three extra nylon shafts nine 2BA Tufflex II Tips a dart mechanic repair tool and a Deluxe Dart Pal Dart Case. The Dart Pal is a great all-in-one solution for your new darts. Featuring a hard outer shell and cloth lined slots to keep your darts secure the Dart Pal has room for everything included in this set!
