Properties: Aura darts with 95% tungsten content provide very good laminar airflow, minimizing turbulence affecting the dart's flight trajectory. Additionally, the barrel surface is coated with blue nitride, making it non-slip, very durable, and giving the darts a unique look. The darts have steel tips and are designed for playing on sisal and paper dartboards. Depending on the weight, barrels come in different shapes and thicknesses.
