K-PRO features TOROLINE's two best selling co-poly tennis strings; WASABI and CAVIAR. This unique blend was designed in collaboration with pro player Karue Sell from My Tennis HQ. The main string, WASABI, is a square shaped co-poly string designed for maximum spin and control. The cross string, CAVIAR, is a hexagonal co-poly string that has exceptional stability and maximum precision.

• WASABI Carbon - Main String (1.23MM)
• CAVIAR Neon Yellow - Cross String (1.24MM)
