They are made from 97% tungsten which is an extremely dense metal compared to traditional brass darts. This makes close grouping of the dart easier thanks to the increased density that allows more weight in a thinner barrel. And because of the weight, strength, and structure, they will last longer over time and bounce outs will be minimised. They are finished with an eye-catching design and include a slimline carry case so you can easily take them with you to your next competition or to a friends house to play.
