Enduraspin is a revolutionary string lubricant that is scientifically engineered to maximize string snapback and reduce friction between the mains and crosses. Putting a light coating of Enduraspin on your racquet's stringbed will provide you with more spin, power and durability. Enduraspin utilizes ProGX Technology that reduces friction between your strings to increase RPM and snapback velocity. Perfect for tennis, squash, badminton and racquetball, this spray is applied before playing and greatly improves the performance of your strings. 

Directions: Apply Enduraspin directly before playing, wipe off any excess with microfiber cloth. Enduraspin recommends that for best results, players should reapply at the end of each set or every hour of play.
