String from Korea, now a hot topic. Developed jointly with the Netherlands. NEVER FAULT - Because I never fail! Available in gauges 118 and 123. Applying twice the amount of coating used in the string industry, we have used a completely new special coating agent. The coating agent is added to the string blend itself, allowing the coating agent to spread evenly on the outside of the string. In addition, the double structure, which injects a certain amount of coating agent inside the string, minimizes friction between the strings. Our advanced coating technology improves the degree of snapback and increases the recovery speed. Dual coated orange gut, improved durability and performance. - Model Name: DUAL COATED MAX POWER - Color: Orange - Features: Dual Layer, Dual Amount Coating - Usage: Tennis racket strings Thank you for viewing.
