The Prime Series Sirius steel tip dart set is designed in collaboration with Yuta Hayashi, the exact dart model used when he won the 2025 Tokyo Super Darts Qualifier.

The 90% tungsten barrel is created with a straight design, featuring a tapered nose and a distinctive step in the centre, supporting a smooth and controlled dart release. Multiple knurled radial grooved cuts provide enhanced finger grip at the front of the barrel, ensuring stability during play. Weighing 23g, with a barrel length of 51mm and a diameter of 6.8mm, these darts offer exceptional control and precision.

The darts are equipped with Nano Swiss Points, featuring a patented locking system for easy point replacement using the included SP tool. This technology guarantees secure points that remain in place during play and allows for quick point changes, ensuring uninterrupted gameplay.

The set includes K-Flex intermediate integrated flights and shafts (26mm), offering a unified design that optimises flight stability and consistency by maintaining 90-degree angled flight petals. The shaft section is specially engineered to move upon impact and reduce bounce-outs during gameplay.
