JS-12 II has an eye-catching painting, matches perfectly with the streamline watermark sticker, and even delivers a stronger sense of speed. The style setting of ?easy swinging and comfortable hitting further makes it a distinctive Speed racket. Having been through years of growth and evolution, as well as the integration of material and technology, JS-12 II not only bears the spirit of speed, but also ignites our inner passion!
