In 1954, GOSEN made history by creating the first synthetic racket strings called HY-SHEEP. Over time, we improved the product by adding a special coating, resulting in the OG-SHEEP tennis string, which boasts high durability and well-balanced performance. Both beginner and advanced players have trusted and used OG-SHEEP for many decades.
