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, which is non-slip, very durable, and gives 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. Packaging may differ from the picture.
