Dart players, these CUESOUL integrated shafts are seriously cool! The ROST system combines the shaft and flight into one solid piece, so no more ripped flights from Robin Hood shots or bounce-outs. The special material is this perfect balance between hard and soft - flexible enough to prevent damage but rigid for consistent flight. The medium length (28mm from screw to flight joint, 74mm total) works great for most throwing styles. The diamond shape flights are precision molded at perfect 90-degree angles for super stable flight paths. The pink color really pops on the dartboard too! Since they're all one piece, you'll never have to reassemble loose flights during a game again. The threading feels smooth and secure in the barrel. Comes as a set of three, so you've got spares ready to go. Available in 9 different colors if pink isn't your thing. Seriously, if you're tired of constantly replacing torn flights, this integrated system is totally worth trying out!
