Harrows Silika Dart Flights - Std - No6 - Damon Heta v2. Made using a premium 100 micron material, these flights are printed and then coated in a unique new Silika coating, significantly increasing the strength of the flight and minimising damage. Similar to sandpaper, the surface of the flight is coarse which increases surface area. When thrown, the increased surface area reduces the speed of the dart in-flight and stabilises the dart’s flight path. Each pack contains 3 flights.
