CUESOUL AK4 TERO Flights & AK7 TERO Shafts

These innovative TERO AK4 flights are a new patent system from CUESOUL. They are well-designed with a built-in spring and telescopic and rotation combo system.  They will absorb follow-up dart impact and turn to reduce errant deflections.  The spring also prevents the flight from rattling during your throw which can happen with repeated usage of other spinning flight brands.
