The Doinkit Dart set was designed with one thing in mind... To develop the best playing magnetic dart set on the planet. Each of these acclaimed Doinkit Darts uses N-35 Neodymium rare earth magnets (Neodymium is a more expensive magnet than Aluminum Nickel Cobalt (Alnico) and of course much more costly than standard ceramic magnets). Combined with space-age Doinkit material that is light, durable and keeps the dart always flying perfectly true, this may be the perfect dart. Comes with 6 perfectly balanced (6.23 gms.) darts with Neodymium magnets that will work on any magnetic dartboard.
