Set of darts: The Windson ROUGE 16 G TUNGSTEN SET is a professional set for real players. The cool red and silver design evokes a sense of speed. The barrels of the ROUGE are made of 95% tungsten weighing 16 grams and are in a silver finish. The flights of the ROUGE set are 150 microns thicker than standard ones. This fundamentally strengthens their structure and prolongs their life.
