1. Precise and Practical Barrels: Knurled grooves at the front and deep - cut grooves in the rear part provide a comfortable firm grip and minimize the sticking effect to the fingers when releasing darts, which is important for a good trajectory and better control during throws. The barrels are weighted 16g, and a completely assembled dart will be 18g. They are suitable as a Christmas or birthday gift for those new to darts, and also a nice gift for your father. 2. Tough Flights: Measuring 0.3mm, the included flights are among the thicker ones available in the market and can last a relatively long time. Meticulous designs also give the whole dart a special aesthetic feeling. 3. Unbreakable Alu Shafts: Light - weighted, slim - shaped Alu shafts give the dart good balance. Each shaft comes with an anti - loosening O - ring placed around the standard 2BA thread. 4. Flight Protectors Accessories: Insert a flight protector at the end of the flight to protect the flight from being damaged by the next thrown dart. The flight protectors also help maintain the shape of the flight, which is beneficial for the dart's balance while flying. Please note that they need to be nipped off from the surround of the plastic disk. 5. Strong Soft Tips for Electronic Dartboard: These durable plastic tips are made of good - quality material with a smoothly transformed shape. They are suitable for any kind of electronic dartboard. The matt surface is specially designed to help the dart stick to the dartboard and reduce bounce - outs. 6. This item offers a unique and practical combo with an astonishingly designed gift packaging and a tool kit. The tool kit can prevent the shafts or soft tips from loosening during a game. You can use the tool to tighten the shafts and soft tips, and also use it to remove a broken soft tip from the barrel.
