The plastic material is stronger than previous models and is harder and more weight. The surface has a leather-like texture. The size, shape, and use of the paddle is the same as the previous stroke maker, so you can use it with confidence. Not just a paddle for strength gaining, but also a training item to achieve an ideal stroke. The multiple holes on the paddle are designed for water flow resistance to reduce the burden on your shoulders. From catch to pull to finish, it dramatically improves stroke technology and connects to your ideal swim. The fingers and wrist can be fixed so you can swim without any worries.
