TARGET PRIME DIAMOND GEN 4 Kosuzu Iwao 90% Tungsten Darts – 22g / 24g

The TARGET PRIME DIAMOND GEN 4 Kosuzu Iwao 90% Tungsten Darts represent the fourth generation of the DIAMOND series, developed in collaboration with Japanese player Kosuzu Iwao (いわお小鈴). This model blends aesthetic elegance with high-performance precision.

 Triple Diamond Ring Design

At the core of the design is the signature triple diamond ring motif, inspired by stacked jewelry rings:

• three distinct grip zones with varying textures and depths
• natural finger placement and easy grip reference
• improved control and reduced slipping

It delivers a perfect balance between style and functionality.

 Red Line Accents

The red detailing:

• enhances the modern DIAMOND aesthetic
• reflects energy, confidence, and passion
• adds strong visual contrast and identity

 Grip & Shape – Precision for Every Throw

• Straight barrel profile – versatile and well-balanced
• Front section – softened shark cuts for smooth release
• Center section – diamond pattern with ring cuts for feedback and control
• Rear section – mild shark grip for stable handling

The grip layout supports a wide range of throwing styles.
